Masterlist

Amphitrite had been gifted a premonition and the world was all the worse for it. The dream had come from Apollo or perhaps the Oneiroi or whatever great heart pumped blood and Gods and monsters out into the world.

It did not matter to the Goddess from whom the vision came, for in this dream Amphitrite had watched her husband fall in love and sire a child to a mortal paramour. A precious boy that Poseidon might even one day love, with a taste for the colour blue and a heroism that would grow to rival his namesake. And for the Queen of the Seas, that simply would not do.

It would not be the child’s nor his mortal mother’s fault – she was not Hera after all – and so she would have to punish her husband for the blame would be his. But how was one to punish a King among Gods before his crime even came to be? Why to beat him at his own game, of course.

So, Amphitrite set out to sire her own demigod with the mortal man her husband would hate most. A devout catholic.

Amphitrite stayed with her mortal lover and their half-blood daughter until the girl was all but five. Far longer than the greater Gods were wont to spend with their offspring. But what a precious babe she had bourn and what a traitorous husband she had back home.

But fate and prophecies and soulmates were such funny things. Inciting chaos. Inviting paradox. Introducing dangers untold.

It took Amphitrite all those years – though seemingly short in her immortality – to realise her fatal error. She had been the one to leave Poseidon. She had been the one to sire a child. She had been the one to drive her husband to the surface and his mortal. And so, the blame was hers to shoulder.

Amphitrite decided that she would be a self-fulfilling prophecy no longer. It was time to venture back below the surface.

In a last fit of guilt, she bestowed her first and final act of mercy unto her mortal lover. She told him everything.

When finally, she had gone back to the sea to reconcile with her husband, the catholic man took his turn to bestow his first and final act of mercy unto his young demigod child.

Against all the teachings of his faith. He abandoned his young daughter at Half-Blood Hill. And let the devil-spawn keep her life.

The Spirit of the Hudson River never did learn to like you. You with your greedy hands, snatching debris from its murky waters. You and your strange sea creature friends who would not dare brave such pollution were it not for your presence. Your pile of war spoils tossed aside like children’s toys. Your strange little bubble of air on the sandy floor of the river, where you stowed your treasures and slept bracketed by water. Were it not for the pollution that slopped against the edge of the river as if it were trying to escape you, the Hudson River Spirit might have chased you and your sea friends and your collection of trinkets out of his waters. But as it were, you made a strangely amicable tenant for a demigod. So, as long as you paid your dues the spirit let you keep your little underwater oasis.

For your first years living there, you made your way in New York City by selling lost things dredged from your river home. Bikes and old weaponry and tarnished jewellery and buckets of coins from across the world. You were careful and you coveted your few precious belongings, but with the rivers bounty, you rarely went hungry.

By the time you were fourteen, you found you could venture further into the city without as many questions. You had met an odd assortment of people whilst selling the lost and unloved things of the river; all who knew someone, who knew someone, who needed another set of hands and so you offered yours. You babysat and cleaned, worked in delis and sandwich shops, helped old women with their groceries and young families mend their clothes. A retired teacher gifted you packets of schoolwork and with little else to fill your hours under the river you took to learning. Your numbers came easier than letters and reading always gave you a hard time but the activities she gave you each time you tended to her balcony garden gave you something to do when the sounds of the city kept you up at night.

All the while you followed Percy Jackson from the recesses of the Hudson. Shuffling your little bubble and its blessedly dry treasures up and then back down the river as he was bounced listlessly from school to school. Watching over him as the mythosphere tried desperately to barge into his little mortal life. Feral harpies that tried to snatch him into the air, great snakes that tried to sneak through air vents and all manner of underworld-born sea creatures that sought to pull him below. You had wrestled and dismembered and slayed them all. Adding their feathers and scales and great weapons to your dragons-hoard.

You were sixteen when you finally knocked on Sally Jackson’s door to introduce yourself. You had spent weeks working yourself up to it, planning your outfit and then fussing over each piece. All your clothes had been gifts and were often a size too big or printed with some generic tagline like Spread peace not hate!; or made entirely from yarn that the old woman whose meals you prepped at the start of each week had gifted you after she had taught you how to crochet; or like the dress you wore now, were sown together from thrifted fabric scraps and embellished with pretty shells and baroque pearls. You had planned the time you would arrive down to the minute so that her oppressive husband would be out, but the hour would not be so late as to make an unexpected visit threatening. You had planned to keep Percy safe while you were away from him by entrusting your friends Clarence the Crab and Emily the Squid to supervise him for the evening.

What you had not planned for was the possibility that Sally Jackson would be the most lovely woman you had ever met. You had been struck dumb by it the moment she opened her door and greeted you with a kind smile. Couldn’t your mother have chosen a mortal as gentle as she to be your parent? Alas, the Gods had never done a thing for you.

“Can I help you, lovely?”

You tried not to burst into tears as you asked, “Mrs. Jackson?”

“Are you alright?” She opened the door wider, leant out and scanned the corridor behind you. “Is there something you need?”

“No ma’am. I’m here about your son, Percy. His father sent me.” A good ambiguous statement that would pique her curiosity but let on nothing about the Gods. Allowing you to spin your tale – that you were Percy’s long-lost step-sister, come to reconnect.

“Poseidon?” Alas, the Gods had truly never done a thing for you. “Is something wrong? Is Percy, okay?”

“He’s fine Mrs. Jackson, I’ve been keeping him safe.”

She scanned the hall behind you once more, “You best come in.”

Over a cup of tea, you told Sally Jackson everything.

You liked your home under the river. For lack of a better term, it allowed you to remain liquid. You could follow Percy wherever trouble took him. You could stay up until the city grew quiet for that brief moment before dawn. You could train with the Hudson River Spirit, even if he only entertained you because he enjoyed winning.

You liked your bed made out of stacked wood pallets and a mountain of blankets. You liked your wooden chest of draws stuffed full of trinkets and weapons and the precious few items you owned. You liked this place that you had carved out with your own two hands.

But you also liked your home in the Jackson household. Where there was always music playing. Where it was always warm and dry. Where there would always be some blue-ified food in the oven or blue candy in the mason jars by the sink.

It became your job in the summers to babysit Percy, to keep him away from Gabe and from danger while entertaining his endless need for motion. You took him to art galleries (which he hated) and aquariums (which he loved), to craft fairs (which he tolerated because he liked the things you made) and swimming pools (which he only liked when he won your swimming races).

“What even is a soulmate?” Percy had asked you one day at the park.

“The person with the other half of your soul,” You scrunched your nose up, “Or well, that's what people say.”

“You’re saying I’ve been walking around with half a soul?”

“I didn’t say I believed them,” You rattled your water bottle in front of his face until he took it. “Stay hydrated.”

He frowned at you, “You don’t believe in soulmates?”

“Of course I do, but it's a little more complicated than that, kid.” You took the water bottle back and played with the cap for a moment while you thought. “Think of it like this. You can have two different puzzles that are cut the same way, right? So all the pieces from one will fit with all the pieces from the other. But that doesn’t mean they belong together, the picture doesn’t come out quite right because even though the pieces fit, they don’t necessarily belong to the same puzzle. Maybe that’s what it was like for your mom, like she couldn’t find the pieces that made up her picture and so she went with the ones that fit at the time.”

“You don’t think my mom and dad were soulmates?”

“I never met your father.”

“But he’s your dad too.”

“He’s my mom’s husband. Maybe my mom and dad are soulmates.” Percy didn’t seem to like that answer. “Maybe it doesn’t matter. Maybe your mom and my mom each have pieces that fit into your dad's puzzle but neither match his picture, or both. Maybe his picture is a year with your mom and a lifetime with mine and having you. Maybe he needs to collect all those little pieces at the right time when they’re the right shape or he’ll end up with a completely different picture at the end.”

“I kind of understand.” But he gave you a look that said he probably didn’t. “What picture are you making?”

You hid your smile behind the lip of your water bottle, “My soulmates about yay-high, pretty as a magazine cover with dimples and all. I’m collecting my puzzle pieces with you and your mom and this city so that I’ll have half of his picture.”

“If you know who he is, why don’t you just go find him now?”

“Still looking for some pieces, I guess.” You kicked a rock with the toe of your boot. “Souls are fragile. If you go rushing in and trying to jam the pieces in when they’re not shaped right just yet you could damage them.”

“What happens if you do that?”

“It’s probably harder to find each other in the next life. You’ll chip pieces away and your souls won’t fit right.” You shoved your hands into the pockets of your cardigan and pulled out a sandwich, you gave Percy the bigger half.

“Who taught you all this?”

“My mom used to tell me and well, I've thought about it a lot.” You tugged Percy by the back of his shirt so he didn't go stomping through a puddle, he glared. “But anyway, some people think it’s just fate. That you find your soulmate no matter what and it’s a perfect fit either way.”

“It would be easier that way.”

“Sometimes that’s just not how the story goes, kid.”

Percy thought that was the most important thing anyone had ever taught him, but he figured some of the other stuff you taught him came in handy too. You taught him the tricks you learned to work around your dyslexia. You taught him to skip stones and to not throw rocks at seagulls. You taught him to flip off the Empire State Building but only when his mom wasn’t around. You taught him to knit and do a cartwheel and make a good cup of tea to take his mother in the morning. You taught him to chew with his mouth shut and to sword fight with wrapping paper rolls. You taught him to braid hair and throw a punch and say all the swears in Ancient Greek.

And then one day, a Satyr came for Percy Jackson, and there was nothing left for you to teach.

You wrote Sally a brief letter of warning, picked your way through seven years’ worth of belongings and collapsed your life into a backpack. You said goodbye to Clarence and Emily with a brief promise to visit, pushed a final wave of pollution from the waters and thanked the Hudson River Spirit for his hospitality. He gifted you sixteen perfect round pearls and insisted that he never wanted to see you again. You spent the bus ride to Long Island threading them into a necklace made of fishing wire, tying off each pearl with your teeth.

It was a tentative tradition between demigod soulmates to exchange gifts upon their first meeting. So few and far between were the possessions of a half-blood that even the smallest bauble would likely mean the world. The practice had died out some over the centuries as the Gods received fewer offerings from mortals and turned to their children for sacrifices. Gift-giving to your soulmate as a demigod became all but synonymous with spitting at the feet of the divine and loudly proclaiming you would make offerings to your soulmate instead. A pearl necklace would be an excellent final addition to the collection of small gifts you had assembled over the years. Let the Gods weep at your feet and beg for scraps if they needed them so much, you would ignore them just as they had ignored you.

You arrived at Camp far sooner than you might have liked, a few hours past mid-day when hopefully the rest of your ilk would be occupied with meaneal chores and activities. You considered waiting at the crest of the hill for someone to notice you only to find a pine tree planted firmly at its peak where you might have stood. Instead, you make the alarmingly easy trek down to the Big House.

“Chiron!” He had always been your favourite of the two men, currently sat on the porch drinking juice and playing cards.

“Yes, my girl?” He barely spared you a glance as he shuffled his cards between his weathered hands. He stilled for a moment and then tossed his head back in the way a horse might toss its mane. “My dear!”

You raised a hand, halfway between a salute and a wave, “Nice to know I haven’t been totally forgotten.”

“Au contraire.” Mr. D stuck his nose up at you. “Which one are you again?”

“The little one that went missing some seven years ago,” Chiron stood as you climbed the stairs onto the porch. “How are you, my dear? Where have you been?”

“Shouldn’t you be at Yancy Academy?”

Mr. D’s eyes turned sharp in the way that had once made your friends whisper that some days, he was more maniac than man , “And how do you know about that little girl?”

“Percy Jackson is at Yancy,” You smiled at him, all teeth, “How did you think he survived long enough for your baby satyr to find him?”

“You have been protecting young demi-gods?” Chiron asked wearily.

“Percy Jackson is a full-time job, I’m afraid,” You tugged at the strap of your backpack, praying you could keep control of the conversation. You had a lot of time under the river to think and this was one of many things you had spent countless hours mulling over. Weighing and considering what story you would tell them – to tell the truth of both your parentage and put Percy in harm's way or to lie and balance your life on its sharp edge. “I found him in Manhattan, he was like a magnet for mythological activity. By the time I’d had enough of rebelling and wanted to come back to camp, I was protecting him from attacks every other week. He wouldn’t have lasted a month. I came back as soon as I could.”

No matter how many times you played it out in your head, the lies won every time.

“Kids.” Mr. D threw back the last of his juice.

“Perhaps you should settle back into the Hermes Cabin, dear.” Chiron smiled down at you, the corners of his eyes pinched, “You’ve given myself and Mr. D much to talk about. We’ll settle the issue of your paperwork tomorrow.”

“Of course.” You rustled through your bag, digging up a palm sized statuette that you set onto the table. “Before I forget, I brought you a gift Mr. D.”

“A toy,” He snatched it up. “Oh joy.”

“It’s you, as the mortals’ see you. It’s from the gift shop at the Met.”

“How kind of you, my dear.” Chiron softened, and you watched as even Mr. D’s temper seemed to ease, his hands gentle around the gift as he admired it.

An unseeing piece of plastic for the God who served as no more than a silent observer over the affairs of the camp. Let him choke on his ego, you thought as you left the pair to their discussion.

Cabin 11 was blessedly empty when you entered, but your old bunk was not. A pile of clothes was thrown haphazardly across the bedspread. You snatched a sleeping bag and a lumpy pillow from the storage closet and threw them down with your bag. If you could not have the bunk that had been yours at twelve, you would claim the corner that had been yours at five. As you shook out the sleeping bag and pulled out your belongings, you tried not to think of your bed of blankets under the river or Sally Jackson’s couch.

Instead you turned your mind to the Big House and the conversation that was no doubt happening within.

You had constructed a perfect image, if you did say so yourself. Grown in ways Mr. D could not have predicted but Chiron would insist he had foreseen. Still a rebellious young woman in the mortal sense, with your scuffed leather boots and ripped jeans. But the parts that had screamed ‘insubordination’ to the Gods were neatly tucked away. Your twin knives strapped to your forearms under the billowing sleeves of your crocheted top, your vicious tongue caged behind a sweet grin, your once sharp stare softened at the edges.

Once you had fashioned yourself so that the Gods could not paint you as a hero, now you fashioned yourself so that they might forget you were an enemy.

Let Chiron think you were a misunderstood wayward girl scout come home from her self-imposed quest. Let Mr. D think you were a stupid girl who had seen the world beyond the Gods’ protection and finally accepted that you needed them. Let them all think wrong. You had left to protect your brother and returned for one reason only.

“You’re here.”

You turned, and there he was, “Luke Castellan.”

He opened his mouth and then closed it, limbs jerking slightly as if he wasn’t sure whether to move toward you or stay put. He was almost certain you could hear the way his pulse was racing, his heartbeat clanging wildly in his chest as he searched desperately for a suave reply, but everything else seemed lack lustre when you said his name like that.

Your face twisted into something like anger and for a moment he thought he’d messed it all up before your lips curled and you practically spat, “I do like your scar.”

And then he was laughing at you, wild and bewildered and not the least bit contained. Before long you were laughing too, neither of you quite sure what was funny, just so wholly relieved as your chests were flooded with wonder and warmth.

It felt like fireworks and popping candy. Just as he had promised all those years ago. You resisted the urge to throw up on his Converse.

You might have been crying and he might been too but you weren’t exactly sure because one moment you were both laughing at nothing and the next he was on the floor with you. He held you like he had never held a single thing in his life, like he was lost at sea and you were the only solid thing for miles. He tucked your head under his chin and sucked in great forced breaths that you could feel beneath your cheek. Because he was warm and there and real. And that meant the last seven years, the better part of your life, hadn’t been for nothing.

You and Luke make your way to dinner side by side. You had spent the afternoon rambling about your lives, about your meetings with your future selves, about your home under the river, about his responsibilities as a camp counsellor and yours as your brother’s keeper. He told you about Annabeth and Thalia and the rest of his siblings, you told him about your parents and Sally Jackson and your sea friends. You gave him his necklace which he lets you fix in place at the base of his throat – you do not spend a moment too long running your hand up the back of his neck and through his curls.

He had been almost bashful when he gifted you a watch that matched his, inlaid with twin fragments of mother of pearl taken from the same shell – kind of like your soul had been, he had said. You swear you’ve never owned anything as precious. You let him strap it to your wrist as he tells you about spending a summer diving for it in the lake. And then softly, tentatively, he tells you about his quest.

Luke could have cried from the way you were looking at him alone, so very gently, like you could cradle him with your gaze alone. At a loss for words, you simply whispered, “I am so proud of you.”

His grip is iron-clad and you tell your next story with your face pressed into the side of his neck, pretending you can’t feel him shaking softly.

When you make your way to dinner you’re both glowing with the soft exhaustion of emotion. You all but lean against one another as you collect your goblets and fill your plates.

The other campers steer clear of you, content to leave Luke to chauffeuring the new kid around. You count yourself lucky, it was only a matter of time until one of the older campers recognised you.

You were almost to the end of the Hermes table – that perfect spot at the end where you might just have a chance of holding a private conversation after dinner – when Chiron interrupted you.

“Mr. Castellan, I see you’ve acquainted yourself with our newly returned camper.”

“That’s my job, sir.” You tried not to stare at the crooked smile he flashed the centaur.

“Perhaps you ought to show her how to make an offering,” Chiron says pointedly, “She’s been away for a long time, and it’s your responsibility to treat her as you would any other incoming Camper.”

Luke turned to you, his boyish grin still charming but the mirth leaking out of his eyes, “Of course. Do you remember how it’s done?”

“I do. Just not a lot of food to be spared in the mortal world.”

You squinted, the corners of your mouth pulled up in what Chiron would likely mistake for sheepishness. But Luke could see it in your eyes. How your anger had made you pointy in all the places someone your age ought to be soft. He wondered how all the jagged edges of you would feel against all the jagged edges of him. He thought maybe if the two of you were careful, you could make something smooth as sea glass and twice as pretty, together.

You dump a clump of mashed potatoes into the fire with an unconcerned flick of your fork. Luke lops part of his own meal on top of yours, you glare enviously at the reasonable portion he had left on his plate. You hoped the food would burn at the bottom of the braiser.

“Sorry, sir.” You mocked Luke. He stuck his tongue at you once Chiron had turned his back.

You hurried to snag the seat at the end of his table, sliding into place across from each other. You flounder for a moment, wondering whether to draw your legs as far under your seat as they will go or bask in the gentle brush of his knee against his leg. You settle for the latter and try not to evaporate under his gaze, as he stares at you even as you start eating.

Luke realised he’d spent too long staring when you all but groaned, “Don’t tell me I have to sacrifice my dinner to you too.”

He flashed you a grin, then tried to say as nonchalantly as possible,“Is that why you left? So you could enjoy a proper meal every once and a while?”

You stared at him for a long while, “You, future you, told me to leave, to find my brother.”

“Why would I do that? If you had stayed at Camp–”

“That’s almost exactly what I said to you.” You pushed your food around as you stared at a point just beyond his head, he thought for a moment that he could see the neurons firing behind your eyes, like a hundred tiny zaps of lightning, “But I’ve had plenty of time to think about it. And I think you were right to send me away.”

“I don’t think I’ll be hearing that very often.” He dodged the pea you fling at him with a grin.

“I think maybe if I don’t leave, I won’t become this me or do the things I’ve done and maybe that’s important for us or our future or some past you rewrote by telling me to leave.”

“Seems overly complicated.”

“I think it’s supposed to be complicated,” You couldn’t help but admire the quiet skill with which he wielded his cutlery, “If it were easy, we would find each other in every universe.”

He paused, knife aloft, “You don’t want to find each other in every universe?”

“It doesn’t matter what I want.” You speared a leaf of spinach onto your fork to hide your scowl behind as you said, “The Gods have made it this way to keep us separated.”

“We’re together now.”

“Which means they lost.”

Luke watched you for a drawn out heartbeat, then leaned over to transfer the perfect squares of meat he’d been cutting onto your plate.

You took a long moment to chew before you said, “So, your plan to send me after Percy worked.”

“I thought it was your plan.”

“I forgot to ask you whose plan it was.”

“I say it’s your plan.” He took a long pull from his goblet that left his lips tinted red.

“It doesn’t matter what you think.” You passed him a napkin before he could ask, “It’s what you will think.”

“Sure, Precious.” He smothers a laugh into the napkin at the way you scrunch your nose at him, “You know, because you're so protective of your food. Like Gollum with the ring.”

“That’s the stupidest explanation for a pet name I’ve ever heard.” But you’re damn near head down on the table as you laughed. “I definitely got the smarter half of our soul.”

“Then it was definitely your plan.”

You’ve still got a hand pressed to your face to conceal your smile when you say, “What about when I meet you? Any words of wisdom?”

“Try not to fall for me. I can tell you’re pretty charmed but it’s really not appropriate. I’m seventeen, and you’re what? Twenty-four?”

You launched your bread roll at him. You’re twice as incensed when he catches it whilst looking directly at you, “Asshole.”

“Smartass. See, two can play that game.”

Luke can’t help but think you’re just as pretty sneering as you are smiling, like no expression no matter how ugly could detract from your beauty. Maybe you’re like him, he scarcely dared to hope. Maybe you’re something better, another part of him whispered. The way you talk about the Gods and turn your nose up at them, and play their game only when it suits you.

You weren’t vengeful in the way he was. You weren’t the spitting vicious thing the Camp had liked to pretend you were when you weren’t around to prove otherwise. You were worse and better and everything he needed. You were a storm on the horizon, a snake coiled tight. You were better than just angry. You were disillusioned. Not a product of juvenile resentment but true wrath born of awareness. Not the wild foaming-at-the-mouth kind that he had imagined when he had first heard your name. But the dark carefully contained kind he had seen in the face you would grow into.

This, Luke thought, you were the start of everything.

It’s some weeks later when you stick your hands through the grating of the bunk above Luke as leverage to lean over him and croon, “Up and at ‘em, Pretty Boy.”

He pushed his face out of his pillow, curls sticking up at odd angles as he looked at you half-asleep, “What?”

“Remember? Training?”

“No,” He scrubbed sleep from his eyes, “What did you call me?”

“Sickly.”

“I don’t think that was it.” He propped his head up on a fist as he smiled at you sleepily.

It was so disgustingly cute that you had to turn your back when you said, “Just meet me there.”

Luke’s freshly showered and holding an apple core when he deigns to join you in the forest. He tossed the apple at you and you caught it without thinking. You fake gag at him as you throw it further into the forest.

You wiped your hands against his shoulder as you say, “I’m not sure if an apple core counts but that was dangerously close to an Ancient Greek proposal, Castellan.”

“I got hungry.” He shrugged. You squared off across the clearing, stretching as you warmed yourselves up for the ensuing sparring match.

“You’re going to have to do better than that.”

“Is this you rejecting me?” He landed an open hand on his chest and staggered backward. “You wound me, Precious!”

“Was that you proposing? Because I’m,” You wiped your hand again for good measure, scrunching your nose up, “Disgusted.”

“You would be honoured if I had just proposed to you.”

“You should be nicer to me.”

“And go easy on you just because you’re my soulmate? Unlikely.”

“Because, asshole, I’m the one who got you out of chores this morning, or have you forgotten already. You seemed rather grateful for your little sleep-in.”

He unsheathed his sword and twirled it round in his hand, “You’re a bad influence.”

“Like you weren’t ready to worship the ground I walk on when I told Chiron you needed to get my training up to speed.”

“Do you want me to tell you, you’re brilliant?” He pointed his sword toward you with that grin that made you want to hold him down just so you could admire it longer. “You’re brilliant.”

“You’re stalling.” You pull your knives out, one from your boot, the other from your belt. You miss your old clothes with their pretty sleeves and their personality, your camp shirt seems a poor trade in comparison.

“Stalling? Me?” Luke scoffed. “Never!”

“Don’t you have a counsellor meeting at half-past?”

“I do, so please don’t feel bad when you lose. I only have half an hour to wrap this up. You understand.”

“Who’s fault is that Mr. Just-five-more-minutes?”

He gasped in mock offence and lunged forward, his sword swinging at you in a great arch. You leapt back, out of his range, then ducked low and rushed toward him. Luke was quick, in a viciously smooth move he swept his sword at you again. You brought your knives together, bracing as the impact ricocheted up your arms. Admittedly, you were at a great disadvantage given that you were reluctant to throw a knife at Luke’s head – even though he’d demonstrated an impressive ability to swipe your wayward throws out of the air – and that he had an additional several feet of reach on you.

Luke feigned to the right, you lashed out at his left side and narrowly avoided his sword as it came down at you. He whistled slowly as both of you backed up to circle each other for a moment.

“You’ve got moves, I’ll give you that.”

And so the dance went on. Luke struck, you parried or slipped out of his blade's path with a flourish. You struck, Luke swung his sword and slipped around your blows. Finally, you found the chink in his precious armour. He fell back to his right foot when he deflected a blow. You jerked forward. You jabbed the knife clutched in your left hand toward him as you moved in with the right. Just as you hooked a foot around the back of his leg, Luke’s sword made contact with your left shoulder slicing through sleeve and skin. Luke fell backward with a sharp hiss, his sword flying to the side.

In the end you had laid him out flat in twenty minutes. Luke Castellan had spent the last seven years fighting to win. You had spent them fighting to survive. You supposed it didn’t hurt that the greatest swordsman to enter Camp Half-Blood in nearly three centuries was reluctant to let anything sharp or pointed anywhere near you. You secretly thought he might have been going easy on you for being his soulmate after all. You collapsed on the forest floor beside him, your chest heaving to draw in oxygen.

“I’m sorry about your shirt,” Luke huffed.

“Orange isn’t really my colour.”

He turned to you with a wink, “Oh but it is.”

You wave your hand through the air.

“I’ve gotten very good at putting broken things back together over the years.” He tried not to look at the line of stitching that ran from the ankle of your jeans to the rips at your knee. You tried not to look at his cheek. Instead you reached out and trailed your hands across his necklace where the pearls sat snuggly at the base of his throat.

“You’re wonderful.” He brushed his knuckles down your shoulder and they came away red. “Even covered in blood you’re the most wonderful thing I’ve ever seen.”

You groaned, “Sweetness, you can’t just say–”

“You call me Sweetness when you visit me.” He whispered it like it was his greatest secret. You traced up his throat to his cheek and pressed your thumb into his dimpled cheek. “You’re still being wonderful. I can’t think when you’re–”

“Wonderful?”

“Okay, Smartass.” He sighed up at the sky, then pulled the both of you to your feet, “Enough lounging, we need to get that cut checked.”

You let him dust the dirt from you and resheath your knives, one in your boot, the other in your belt. Silently revelling in the gentle way he tugs you this way and that. You were well on your way to the infirmary, shoulders bumping and fingers just barely brushing, before he spoke again.

“Where does it come from? The nickname.”

“Sweetness?”

He looked away from you and squinted off into the distance, as if you were suddenly too bright to look at, “Yeah.”

“My mom used to tell me this story about meeting her soulmate. She probably meant Poseidon, but at the time I thought it was about my dad,” The back of Luke’s hand bumped into yours again, his fingers catching yours, his gaze resolutely ahead but you were definitely holding hands. “She said it felt like swallowing lightning and gorging yourself on popping candy. Like sweetness.”

“You like popping candy?”

“It’s my favourite.” You gave him a queer look as if to say, it’s not yours, you utter heathen?

Luke laughed at you all the way to the Apollo Cabin as he listed all the reasons it was the sub-par candy option. Nonetheless, when you emerge from the infirmary, he unloads a fistful of little packets he’d pinched from the candy bowl when the Apollo kids’ hadn’t been looking.

“Who has sub-par candy options now, Sweetness?” You teased, your mouth crackling merrily.

“Keep calling me that and you can have all the terrible candy you want.”

“Try some,” You shoved a packet toward him, because if he kept saying silly things like that and looking at you the way he was you were liable to do or say something equally as stupid. “You’ve got half my soul, maybe it’s our favourite.”

“I don’t think they had popping candy when we had one soul,” He flicks the packet held between your fingers. “And aren’t you the one who says we’re puzzle pieces not halves?”

“You have been listening to me!”

“Hard not to.”

“Asshole.” You flashed your teeth at him.

“Smartass.” He said, but the bite wasn’t there. He was watching you again, in that way he did sometimes before he said something stupid that made you want to throw yourself in the lake or run back to Manhattan or do something equally as stupid, like kiss him. “You–”

You twisted your hand in the front of his shirt and jerked him toward you, the little sachet crinkling in your fist. For a heartbeat, you were both silent, an inch away and staring as if you could will the other to be the one to press forward. But then he closed his eyes and Luke Castellan was kissing you. Like lightning and popping candy. With all the elegance of two lovestruck teenage fools and all the heat of two people who knew they had all the time in the world but still couldn’t bear to waste a second of it. His hand held you by the chin and then splayed lightly across your cheek and tucked hair softly behind your ear. You were only just reaching for the mess of curls at the back of his head when someone wolf whistles.

“My favourite.” Luke grinned, licked his lips and then turned. Hands stuffed in his pockets and a big stupid grin stretched across his face, as he shouted at you, “Stay out of trouble.”

You flip off the Aphrodite kid who’d whistled at you, and hurried back to the Apollo Cabin. You and Luke Castellan were going to need a lot more popping candy.

You’re in the lake, encased in an air bubble, sprawled out side by side with your backs against the sand, when Luke tells you what he’s done. That mere weeks before your arrival he had done the unthinkable. He had robbed the King of the Gods blind and betrayed half the Pantheon in doing so. You weren't sure whether to laugh or cry.

You had simply laid there, silently, for what had felt like aeons to Luke but maybe that had only been because he had to keep reminding himself not to hold his breath. He wasn’t drowning. You weren’t going to turn him in. He hadn’t just blown his whole plan and his life with his soulmate in one fell swoop. He just had to keep breathing and wait for you to say something. He thinks that maybe your mother had passed on some divine knack for diplomacy as Queen of the Sea with the way you seem to turn the issue of his betrayal over and over in your head.

After a while, you reach your arm toward the bubble and the sky. For a brief, terrifying moment, Luke thinks you’re going to pull the lake down on him. When you don’t Luke spends another infinite second wondering whether he would just let you do it.

He tosses the thought aside and focuses on the coin weaving between your knuckles. Like magic, it appears and disappears around the bends of your fingers but it wasn't real magic, just you fidgeting. He pressed his lips together and tried not to think about you at the bottom of the Hudson River, flipping your coin and turning over the issue of your soulmate and your brother and the camp you’d left behind. What is it you had said? You’d had plenty of time to think about those things.

Maybe that's what you need now – time. He’s about to offer it to you, offer to swim his way back to shore so you can think, even if he'd probably drown on the way. He’d give you all the time in the world if he had it.

But then you finally speak, the golden drachma rolling between your fingers, “If you hurt my brother, soulmate or not, I will kill you.”

“I am your soulmate.” He insisted as the implication made his skin itch.

“You are.” Your smile was so gentle it almost felt sad. “So you understand that my love for him comes before my hatred of the Gods. If you have put him in danger wit–”

“We get married.” He blurted. “We have a future. I woke you, when you visited me. That must mean I win.”

“It means, if that’s the path we’re even on, if those people are even the versions of us that we become… maybe you don’t hurt Percy.”

“I won’t.” He swore and you weren’t sure how to ignore the half of your soul that lies so sweetly. “I wouldn’t.”

“Maybe.” You swallowed like you’d been chewing glass your whole life, and someone had finally offered you something substantial to sink your teeth into. “Maybe if we leave now, there’s a world in which I don’t have to pick between my blood and my soul.”

Luke was quiet for a long moment, “We could recruit him. You said it yourself, he’ll be more powerful than any of us.”

“He’s twelve.”

“He’s the son of Poseidon.”

“He’s twelve.”

“You were twelve when you left to protect him.”

“And look how that turned out,” Your grin was brittle, but he swore you were still the loveliest creature he’d ever laid eyes on. “I’m sat here planning to betray everything I was raised to follow.”

“You’re going to follow me?”

Your eyes traced the shape of his jaw, his nose, his scar. You looked pained, “I fear I would follow you into much worse, Luke Castellan.”

“I’m trying to lead you to something better.” He reached for your hand, took the drachma from your fingers, and pressed a slow, soft kiss to your palm. He smiled and there were dimples in his cheeks and tears in his eyes as he whispered, “We can try for better.”

“Leave Percy.” You pressed your fingers to his cheek, “Let him come to camp, let him join us when he’s ready.”

“You’re sure he’ll join us?”

“He will, I know it. We just need to let him see the Gods’ apathy for himself.” And you sighed. Luke wondered how many lifetimes your souls had seen, how many times you had searched for each other, how many times you had been torn apart. You sound ancient when you say, “You and I have seen more than enough.”

He turned his head and whispered in the scarce distance between you, “What do you propose?”

“We leave. As soon as anyone catches on, we take anyone who agrees with us and flee.” You brought his hand to your mouth and pressed your lips to his knuckles firmly, “We can plot your revenge and plan my new world on the way.”

Luke feels ancient when he promises, “Okay, on the way then.”

But he swears, as you lean forward and kiss him, that no matter how many times you do it this lifetime or in all the lifetimes until this story – of you and Luke Castellan – became ancient, it would still never stop feeling like the first time.

Like lightning and popping candy.
