Percy brought a dozen donuts. Glazed, chocolate, and the ones with sprinkles that nobody admitted to liking but everybody ate first.
He got to the bench at seven in the morning, when the mist was still lying low on the canoe lake and the naiads were just waking up, blowing lazy bubbles up through the green water. The camp was quiet. Most of it was sleeping off last night's party. Somewhere over by the strawberry fields, a satyr was playing a sleepy, off-key tune on his reed pipes.
He sat down. He put the box on the bench beside him. He waited.
[THREAD-WORN (Severe): Remaining: 23 hours.]
Not now, he thought, at the fog. Not this. I need my head for this.
The fog didn't care. It never did.
At seven-thirty, Luke came down the path from the cabins.
He had his hands in the pockets of his orange camp hoodie, and his hair was still wet from the shower, and he walked like he hadn't quite decided whether he was coming or not until he got there. He stopped a few feet from the bench. He looked at the donut box. He looked at Percy.
"You actually brought donuts," he said.
"I said I would."
Luke looked at him for a long moment. Then he sat down on the far end of the bench, as far from Percy as he could get without falling off. He took a chocolate one. He didn't eat it. He just held it, and looked at the lake.
Percy didn't push. He ate a glazed donut and watched the naiads, and waited.
It was a long time before Luke spoke.
"I hear him," he said at last. Very quietly. "At night. In my dreams. Since last winter." He was turning the donut over in his fingers. "He's very... reasonable. That's the thing nobody tells you. You think a voice like that would be scary. Screaming, or whatever. He's not. He's calm. He talks to me like I'm the only person in the world who gets it. He says the gods don't care about us. That they make us and dump us and forget us. He says there's a better way." Luke's jaw tightened. "And the worst part is, I keep waking up thinking he's right."
"He is right," Percy said.
Luke's head came around so fast Percy heard his neck crack.
"About some of it," Percy said. "The gods do forget us. They make kids and leave them. Look at Cabin Eleven. Forty kids sleeping on the floor because nobody's bothered to claim them. Look at you." He looked out at the lake. "He's right about the problem, Luke. That's how he gets you. He's just wrong about the answer."
"What's the answer, then?" Luke's voice had an edge now. "Since you know so much."
Percy thought about it. About two lives, and two worlds, and a boy he'd once called a friend dying with a knife in his own armpit on the floor of the throne room of Olympus, because it was the only way left to fix what he'd done.
"I don't know yet," he said honestly. "I'm working on it. But I know his answer ends with you dead."
Luke stared at him.
"He doesn't want to fix anything," Percy said. "He wants to eat it. All of it. The gods, the camp, the world. And he needs a body to do it. A strong one, young, angry. Somebody who'll say yes." He turned and met Luke's eyes. "He's going to ask you for yours."
The chocolate donut crumbled in Luke's fist.
For a while, neither of them said anything.
The naiads had stopped playing. They were floating at the edge of the water now, three green faces just above the surface, watching the two boys on the bench with wide, worried eyes. Even they could feel it. The air was heavy.
"How," Luke said finally. His voice was hoarse. "How do you know that? How could you possibly know that?"
Percy had known the question was coming. He'd thought about it all night, lying on his bunk under the statue of his father, through the fog.
He could lie. He was good at lying now. He could say Hades had told him. Or he'd seen it in a dream. Or the voice in the pit had bragged about it. Any of those would work.
But Hermes hadn't asked him to manage Luke. He'd asked him to talk to him.
And you couldn't really talk to someone while you were lying to them.
"Because I've seen it happen," Percy said.
Luke went very still.
"Not here," Percy said. "Somewhere else. Somewhere a lot like here. I can't explain it all. I'm not even sure I understand it all myself. But I've seen it. I watched you say yes to him. I watched him take you. I watched him wear your face and use your hands, and tear the whole world apart with them." He swallowed. "And at the very end, I watched you take it back. You fought him off, from the inside, and you did the only thing you could to stop him."
He stopped.
"What did I do?" Luke whispered.
Percy looked down at his hands.
"You died," he said. "On purpose. To kill him with you."
The silence after that went on and on.
Luke didn't call him a liar. That was the strange thing. Percy had expected him to. Expected him to laugh, or get angry, or walk away. But Luke just sat there on the bench with crumbs of chocolate donut on his fist, staring at the lake. His face was very pale, and the scar down his cheek stood out like a silver thread.
"You're telling the truth," he said at last. Slowly. Wonderingly. "I can tell. Hermes kids can always tell. You're... gods, you're actually telling the truth."
"Yeah."
"That's insane."
"Yeah."
Luke laughed. It was a short, cracked, breathless sound with nothing funny in it.
"So I'm a villain," he said. "That's what you're telling me. In some other world, I'm the bad guy. I'm the one who—" His voice broke. "Who does all of that. And you came here, and you sat down on my bench, and gave me donuts."
"You're not a villain," Percy said. "You're a kid whose dad left. Who's angry. Who's got every right to be angry. You're the guy who showed me around camp the first day, in that other world. Who taught me to sword fight. Who was nice to me when nobody else was." He held Luke's eyes. "And who, at the very end, when everything was on the line, chose right. Even though it killed him. That's who you are, Luke. All of it. Not just the bad parts."
Luke stared at him.
Then he put his face in his hands.
He didn't cry. Not exactly. He just sat there, bent over on the bench with his face hidden, breathing hard and slow, like someone who'd just been hit very hard and was trying to figure out if anything was broken.
Percy didn't touch him. He didn't say anything. He just stayed.
That was all Hermes had asked for. Stay.
[Great Sage notes: Luke Castellan's thread is... changing.]
[Direction: Uncertain.]
When Luke finally lifted his head, his eyes were dry, and red, and very tired.
"What do I do?" he said.
It was such a simple question. And it was the hardest one Percy had ever been asked.
He wanted to say stay. Stay at camp. Stay here, where I can watch you, where I can keep the voice away from you. Stay, and I'll fix it.
But he knew Luke. He knew that if he tried to cage him, Luke would break the cage, and break himself on it.
"I can't tell you that," he said. "I wish I could. But it has to be you. That's the whole point. If I tell you what to do, and you do it, it's just one more grown-up pushing you around. Kronos, Hermes, Chiron, me. You'd hate it. And sooner or later you'd stop listening." He paused. "So I'm just going to tell you what I know. And then you decide."
Luke waited.
"The voice is going to get louder," Percy said. "He's going to promise you things. Your mom, fixed. Your dad, sorry. A world where nobody gets left behind. And he's going to sound so reasonable. And some of what he says is going to be true." He leaned forward. "But anytime he asks you to hurt someone to get it, someone who didn't do anything to you, a kid, a camper, a satyr, a tree, that's the lie. That's him. Every time."
"And if I can't tell the difference?"
"Then come find me," Percy said. "Wherever I am. Whenever. Doesn't matter what you've done. Come find me, and we'll figure it out together."
Luke looked at him for a long time.
"Why?" he said. "Why do you care? You don't even know me. Not this me."
Percy thought about the answer he'd given Sir Percival. About the Siege Perilous.
"Because somebody should've done it for you a long time ago," he said. "And nobody did."
Luke opened his mouth. Then he closed it again.
He reached over, slowly, and took a donut out of the box. A sprinkled one. He ate it in three bites, looking out at the lake.
"These are terrible," he said, with his mouth full.
"I know," Percy said. "They're from the gas station by the highway."
Luke snorted. And for one second, just one, he looked like the boy Percy remembered from that first summer in another world. Seventeen and cocky and quick to laugh, before the voice had gotten its claws all the way in.
[FAITH: Luke Castellan... considers the Host. +5 Faith.]
[Note: It is a beginning.]
The rest of the summer went by fast.
The Thread-Worn wore off the next morning, and for the first time in a week Percy's head was clear. He spent the first few days doing absolutely nothing. He slept. He ate. He swam in the canoe lake with Lupe, who'd decided she liked water now that she'd met Cerberus. He sat on the porch of Cabin One and watched the sun go down and didn't think about anything at all.
Then he went back to work.
He trained. Every morning in the arena, before breakfast. Sword drills with Proteus, cycling through realm after realm until switching shapes was as easy as breathing. Hand-to-hand with Clarisse, who had declared herself his personal sparring partner on the second day and nearly broke his nose doing it. Lightning practice down at the beach, out where he couldn't set anything on fire. Shadow work in the woods at night, learning to move with them, through them, until stepping from one patch of dark into another felt as natural as walking.
And he went up the tower. Carefully this time. Never more than two days at once. He farmed the cleared floors and sold the loot to the Broker at the Market, and watched the numbers on his System Debit Card climb.
[Thread-Worn avoided. Great Sage is pleased.]
You're never pleased.
[Great Sage is experiencing something adjacent to pleased.]
He trained Ezra too.
That had been the promise, on the van. Will you teach me? So every afternoon, after the other activities, the two of them went down to the beach. Percy taught the son of Poseidon the things nobody had taught him in his first life. How to breathe in a fight. How to watch an opponent's hips instead of his sword. How to fall without breaking anything, and get up again before you were done falling. How to listen to the water instead of yelling at it.
Ezra was terrible at first. Impatient, arrogant, too quick to lose his temper. But he kept coming back. Every single day. And by the end of July, he could hold the tide still for a full minute. He could put Percy on his back in the sand one time out of ten. He could stand in the surf with his eyes closed and tell you how many fish were in the water within fifty yards.
"You're getting good," Percy told him one evening, sitting in the wet sand, rubbing a bruise on his shoulder where Ezra had flipped him.
"I'm getting better," Ezra said. He was grinning, and dripping, and out of breath. "Not good. Not yet. Not like you." The grin faded into something more serious. "But I will be. Someday. You'll see."
"I know," Percy said. And he meant it.
And slowly, without his meaning it to, the camp started to orbit around him.
It started with Cabin Eleven. The unclaimed kids, the ones nobody wanted, sleeping on the floor of the Hermes cabin. They'd heard what he'd done on the quest. And they'd heard, from somewhere, that he wanted to build a place for kids like them. So they started showing up. At his training sessions. At the arena. On the porch of Cabin One in the evening, sitting on the steps, just to be near him.
Then the Ares cabin. Clarisse had said we're in, and she'd meant it. The whole cabin started training with him. Big, scarred, scowling kids who'd never listened to anybody but their counselor, listening to him.
Then others. Beckendorf, from the Hephaestus cabin, who'd heard about the Tunnel of Love from his father in a dream, and who came by one evening to shake Percy's hand and ask, very seriously, how a mortal kid had gotten Hephaestus to smile. Lee Fletcher from Apollo, who'd seen the lightning on the beach. Katie Gardner from Demeter. Silena Beauregard, who said Aphrodite was very interested in the boy who'd turned down the Lotus. The Stoll brothers, who were mostly interested in how he'd robbed it.
By August, there were thirty or forty kids at his morning training. By the middle of August, it was sixty.
[FAITH: Camp Half-Blood's faith in the Host is growing.]
[Faith toward Rank C: 2,940 / 8,000.]
Chiron watched it all from the porch of the Big House. He didn't say anything. But sometimes Percy would look up in the middle of a drill, and catch the old centaur looking at him with an expression he couldn't read.
And Luke watched too.
He didn't come to the training sessions. He didn't come to the bench by the lake again. But Percy saw him sometimes, at the edge of things. Standing at the back of the arena, arms crossed, watching Percy teach a dozen unclaimed kids how to hold a sword. Sitting on the steps of the Hermes cabin at night, alone, turning something small and metal over and over in his fingers. Once, Percy caught him at the edge of the woods by Thalia's pine, very late at night, just standing there, staring at the tree.
Percy didn't push. He'd said what he had to say. The rest was up to Luke.
But every night, before he went to sleep, he asked Great Sage the same question.
Luke's thread?
And every night, Great Sage gave him the same answer.
[Unchanged. Uncertain. Not yet broken.]
On the last night of summer, Luke was gone.
Percy found out in the morning. The whole camp did. Connor Stoll came running up to the dining pavilion at breakfast, white-faced, holding a piece of paper. Luke's bunk was empty. His sword was gone. His pack was gone. Nobody had seen him leave. Not the harpies who patrolled at night. Not Argus. Not the dryads at the border.
He'd just walked out of camp in the dark, and vanished.
There was a note on his bunk. It was addressed to the Hermes cabin. It said he was sorry, and that he needed to go, and that they should listen to Connor and Travis now, and not be stupid. It said he loved them. That was all.
Percy stood in the middle of the dining pavilion while the camp exploded into noise and panic around him, and felt the bottom drop out of his stomach.
Great Sage.
[Luke Castellan's thread has left the boundary of Camp Half-Blood.]
Is it broken?
A pause. Too long.
[...Great Sage does not know.]
The second note came that afternoon.
Percy was sitting alone on the bench by the canoe lake, the same one, because he didn't know where else to go. The naiads were watching him from the water. And a man in a blue delivery uniform with wings on his sneakers was walking down the path toward him, holding a small envelope.
Hermes didn't say anything. He just handed Percy the envelope. His face was very tired, and very old. Then he sat down on the far end of the bench, the same place Luke had sat, and looked out at the lake.
The envelope was plain. The handwriting on the front was quick and slanted and familiar. It just said PERCY.
He opened it.
Percy,
You said it has to be me. That I have to decide.
I can't decide here. Not with him in my head every night and everyone watching me like I'm about to break. I need to go out there and see it for myself. The world. The gods. Him. What he's offering. I need to find out whose voice I'm going to listen to.
Don't follow me. I mean it.
But you said if I can't tell the difference, come find you. Wherever. Whenever. Doesn't matter what I've done.
I'm holding you to that.
L.
P.S. The donuts really were terrible.
Percy read it three times.
Then he folded it very carefully and put it in his inventory, where nothing could ever happen to it.
[Item stored: Luke's Letter.]
[QUEST UNLOCKED: THE PRODIGAL. Keep your promise to Luke Castellan.]
[Type: Personal. Duration: Unknown.]
[Reward: ???]
Hermes was still sitting on the end of the bench, looking at the lake.
"He came to my temple," the god said quietly. "In the city. Last night, on his way out. First time in years. He didn't pray. He didn't say anything. He just stood there for a minute, in front of my altar. Then he left." His voice was rough. "He's never done that before. Not once."
"That's good," Percy said. "Isn't it?"
"I don't know." Hermes looked at him. "I don't know what anything means anymore, where he's concerned. I just know you talked to him, like I asked. And he walked into my temple for the first time in five years." He stood up. "Thank you, Percy."
"I didn't fix anything."
"No," said the god of messengers. "You didn't. But you didn't give up on him either." He paused. "Most people do. Including me."
And he was gone, in a gust of wind and the smell of road dust.
Percy sat on the bench until the sun went down. The naiads came up to the edge of the water and sang something soft and sad in their own language. It might have been for him. It might have been for Luke.
I'll find you, he thought, looking out at the dark water. When you need me. I promise.
Just don't say yes before then.
The next morning, he packed his bag. He said goodbye to Lupe's new friends the naiads, and to Clarisse, who punched him in the shoulder and told him not to get soft. And to Ezra, who shook his hand and said, very seriously, I'll keep training. Every day. You'll see.
Then he climbed into the camp van, and Argus drove him back to Manhattan.
Back to his mother. Back to Goode. Back to Rachel and Nancy and Matt, and a company called Argo, and two islands that didn't belong to them yet.
It was time to get to work.
