The four heroes took over Camp Half-Blood the way a storm takes over a sky. All at once, and completely.
By the morning of the second day, nothing was the same.
Theseus had the whole camp up at five a.m. running laps around the canoe lake. Even the Aphrodite cabin. Even the Hypnos kids, who'd never been up before ten in their lives and kept falling asleep mid-stride. He didn't yell. He didn't have to. He just ran beside them, all six and a half feet of him, barefoot, with his club over his shoulder, and nobody wanted to be the one to stop while he was watching.
Perseus, the original, took over the arena. He taught swordplay in a way Percy had never seen before. Loose and fast and tricky, full of feints and dirty footwork and flat-out cheating. "Monsters don't fight fair," he told a crowd of goggle-eyed campers, grinning, as he disarmed three of them at once. "Why should you?" He spent half of every lesson flying around over their heads in his winged sandals, laughing, dropping water balloons. The Hermes cabin worshipped him within an hour.
Achilles didn't teach anyone anything. He just stood at the edge of the arena, every day, all day, with his spear, and watched. Sometimes he watched Percy. Sometimes he watched the dying tree. Nobody dared speak to him.
And Odysseus.
Odysseus went everywhere. He walked the whole camp in a single morning. Every cabin, every field, the forge, the armory, the stables, the boundary line. Asking questions, touching things, poking things, counting things. He talked to the harpies. He talked to the dryads. He talked to Argus, which nobody had ever done before because Argus didn't talk. Argus talked back, somehow, with his hundred eyes. By lunchtime, Odysseus knew more about Camp Half-Blood than anyone who'd ever lived there.
And at dinner on the second night, he sat down across from Percy at the Zeus table, uninvited, with a plate of barbecue and a goblet of wine, and said, "So. Tell me about the tree."
Percy told him.
The poison. Python's venom, from Tartarus. The boundary. Eleven days, Great Sage had said. Nine now.
Odysseus listened to all of it, chewing thoughtfully on a rib. When Percy was done, he wiped his fingers on a napkin and leaned back in his chair.
"You know how to cure it," he said. It wasn't a question.
Percy hesitated.
Odysseus smiled. It was a slow, clever, crinkled smile. The smile of a man who'd spent ten years lying to monsters and kings and gods and getting away with it.
"Don't bother hiding it, lad," he said. "I've spent a thousand years in paradise with nothing to do but sit around and think about faces. I know what a man looks like when he already knows the answer and is deciding whether to say it out loud." He took a sip of wine. "You have that look. You've had it since I got here. You knew what was killing that tree before anyone told you. And you know what will save it."
Percy looked at the clever old hero for a long moment.
"The Golden Fleece," he said.
Odysseus's smile widened.
"The Golden Fleece," he agreed. "Of Colchis. The fleece of the ram with the golden wool, that Jason and his Argonauts went to the end of the world to steal. It heals anything. Any poison, any wound, any blight. Put it on a dying tree, and the tree lives. Put it on a dying land, and the land blooms." He swirled his wine. "Do you happen to know where it is?"
"The Sea of Monsters," Percy said. "On an island. Guarded by a Cyclops."
Odysseus went very still.
"Which Cyclops?" he said softly.
"Polyphemus," said Percy.
For one long second, Odysseus didn't move at all. His clever gray eyes went very far away. Then he laughed. It was a low, rueful, astonished laugh, and he shook his head.
"Of course," he said. "Of course it's him. Three thousand years, and the gods still have a sense of humor." He put down his goblet. "I blinded that Cyclops, you know. Put a sharpened stake through his one eye, while he slept, drunk on my wine. And then I sailed away, laughing, and shouted my own name back at him from the deck of my ship. Like a fool." His mouth twisted. "He prayed to his father for revenge. His father is Poseidon. And that is why it took me ten years to get home."
He looked at Percy.
"You know a great deal, lad," he said, very quietly. "About things you shouldn't. About the tree, and the Fleece, and the Cyclops. Just like you knew about Asterion's name." His eyes narrowed. "I don't suppose you'd care to tell me how?"
"No, sir," said Percy.
Odysseus looked at him for a long moment.
Then he laughed again, louder this time, and clapped Percy on the shoulder.
"Good answer," he said. "Never tell anyone how you know a thing. Especially not someone clever. Clever people steal secrets for a living." He stood up and picked up his plate. "We'll talk again tomorrow. With the others. And your counselors. We need a plan, and we need it fast." He paused. "And lad?"
"Yeah?"
"When we make the plan, I'm going to need you to say all of this again. In front of everyone. Including the Fleece, and the Cyclops." The clever eyes glinted. "But I'm going to need you to say it like you've just thought of it. Not like you've known it for a year."
Percy stared at him.
Odysseus winked. And walked away.
[FAITH: Odysseus, the Clever One, has taken an interest in the Host. +150 Faith.]
[Great Sage notes: Great Sage likes this one.]
That night, Percy dreamed of Grover.
It wasn't a normal dream. He knew that right away. It had the sharp, too-real edges of the dreams that came through the empathy link, the one the two of them had shared since the bus in New Jersey. He'd almost forgotten about it. Grover had been gone since September, out in the world with his new searcher's license, looking for Pan.
He was in a cave.
A huge cave, high-roofed and dark and stinking of sheep. There were sheep everywhere. Big ones, woolly and white, crowding the floor, and every single one of them was staring at Percy with flat, hungry eyes. Bones were scattered around the walls of the cave. A lot of bones. Some of them were sheep bones. Some of them weren't.
And at the back of the cave, sitting on a pile of rocks with his head in his hands, was Grover.
He was wearing a wedding dress.
It was huge and white and lacy and made for someone three times his size, and it puddled around his hooves on the cave floor. There was a veil on his head, crooked between his horns. He looked like he'd been crying for days.
"Grover!" Percy said.
Grover's head snapped up.
"Percy!" he squeaked. "Oh gods, oh gods, it worked, it actually worked, I've been trying to reach you for days—"
"Where are you? What happened?"
"I followed a scent," Grover babbled. "A nature scent. The strongest one I've ever smelled. I thought it was Pan. I thought I'd finally found him. I followed it for weeks, Percy, all the way across the ocean, and it led me here, and it wasn't Pan at all. It was the Fleece. The Golden Fleece. It gives off a smell like a god of nature. That's how he lures satyrs in."
"Who?"
The ground of the cave shook.
Thumping footsteps, enormous ones, came from somewhere outside the mouth of the cave. And a voice. Huge and booming and terrible. And cheerful, in a way that made it a thousand times worse.
"Cyclops-ette! Cyclops-ette, my bride! Are you ready for the wedding? Only a few more days! Then we will be married!"
Grover's face went the color of curdled milk.
"He thinks I'm a girl Cyclops," he whispered. "He's half-blind. I put on the dress and I made my voice high and I told him I was a Cyclops-ette, so he wouldn't eat me. And now he wants to marry me. On the solstice." His voice cracked. "Percy, when he finds out, he's going to eat me. And I can't stall him much longer."
"I'm coming," Percy said. "Grover. Listen to me. I'm coming. I'll find you. Hold on."
"Hurry," Grover whispered.
And the dream tore apart.
Percy woke up in his bunk in Cabin One with his heart hammering, sweat pouring off him, and Lupe whining on his chest.
[EMPATHY LINK: Grover Underwood. Status: Captive.]
[Location: An island in the Sea of Monsters. Same location as the Golden Fleece.]
[Time until the Cyclops's wedding: 9 days.]
He lay in the dark, staring at the ceiling.
Nine days, he thought. Nine days for the tree. Nine days for Grover.
Same island. Same deadline.
He got up, and went to find Odysseus.
The meeting was in the Big House, at dawn, around the ping-pong table.
It was crowded. All the counselors who hadn't left for Plum Island. Clarisse, Annabeth, Castor and Pollux, the Stolls. Ezra, now officially counselor of the Poseidon cabin, with Tyson looming behind him because Tyson refused to be more than three feet from his brother. Dionysus, slumped in his lawn chair. And the four heroes, sitting in a row at the far end of the table. Odysseus in the middle, with his hands folded and his clever eyes moving from face to face.
And Percy. Standing at the head of the table where Chiron used to sit.
He didn't remember deciding to stand there. He'd just walked into the room and gone to that spot. And nobody had said anything. Clarisse had just nodded at him. So had Annabeth. So had the Stolls. Even Dionysus had only rolled his eyes and muttered something about "teenagers."
The Hill's Chosen, Percy thought. That's what the title meant.
He took a breath.
And he said it all. The way Odysseus had told him to. Like he'd just figured it out.
The tree. The poison. The Fleece, and what it could do. The Sea of Monsters. The dream of Grover, in the cave, in the wedding dress. The Cyclops, Polyphemus, who'd stolen the Fleece and was using it to lure satyrs to his island to eat them. Nine days. Same island, same deadline. One quest to save them both.
When he was done, the room was silent.
Odysseus was smiling faintly at the far end of the table. He gave Percy a tiny nod. Well done, lad.
"The Sea of Monsters," said Theseus slowly, in his deep voice. "It is a hard sea. Harder than any on earth. I sailed it once, as a young man. I lost half my crew."
"I sailed it for ten years," said Odysseus dryly. "I lost all of mine."
"Ha," said Perseus. "I flew over it. Didn't lose anybody." He grinned. "Winged sandals. Highly recommend."
Achilles said nothing. But his sad eyes were fixed on Percy.
"A quest, then," said Dionysus, from his lawn chair. He sounded bored, but his purple eyes were sharp. "Obviously. Somebody goes to the Sea of Monsters, steals the Fleece back from a one-eyed lunatic, rescues the goat-boy, comes home, and saves the tree. Simple." He sipped his Diet Coke. "So who's going to lead it? Somebody's got to go up and talk to the mummy."
Every eye in the room turned to Percy.
And before Percy could open his mouth, Clarisse stood up.
"Me," said Clarisse La Rue.
The room went quiet again.
She was standing very straight at the table, with her arms at her sides and her jaw set, and she was looking at Percy. Not at Dionysus. Not at the heroes. At Percy.
"I want to lead it," she said. "I'm asking you to let me."
Percy looked at her.
In his first life, Clarisse had led this quest. She'd gone to the Oracle and gotten the prophecy, and sailed to the Sea of Monsters on a ship full of zombie Confederate soldiers. Percy had followed her, without permission, because he couldn't stand to sit at camp while Grover was in danger. And at the end of it, she'd been the one who brought the Fleece home, on a pegasus, alone, with tears in her eyes, because Percy had told her she needed to be the hero this time. She needed to make her father proud.
He'd thought it was the right thing to do, back then. Giving her the glory.
He still thought so.
"Why?" he asked quietly.
Clarisse's jaw worked. For a second Percy thought she wasn't going to answer. Then she did.
"Because my dad came to me last night," she said. Her voice was very low. "In a dream. First time since you put him in the sand." She swallowed. "He was... I've never seen him like that. He wasn't yelling. He wasn't laughing. He just sat there. And he said, They're saying a mortal beat me, kid. My own daughter's friend. The whole mountain's laughing at me." Her fists clenched. "And then he said, Bring me the Fleece. Bring it home. Show them a child of Ares is worth something."
She looked at Percy, and her eyes were fierce and bright and very wet.
"I know I'm not you," she said. "I know I can't do what you do. Lightning and dragons and whatever. But I'm the best fighter in this camp, after you. I've been training my whole life for this. And I need to do this, Jackson. I need to do this one thing myself." Her voice broke, just a little. "Please."
The room was completely silent.
Percy looked at Clarisse for a long time. At the daughter of the god he'd humiliated. Standing at a ping-pong table in front of four of the greatest heroes who ever lived, asking for the chance to fix it.
Then he nodded.
"Okay," he said. "It's yours."
Clarisse stared at him.
"Just like that?"
"Just like that," Percy said. "You lead. Go talk to the Oracle." He paused. "But I'm coming with you. If you'll have me."
For a long moment Clarisse didn't say anything. Then she grinned. The shark grin, the one she'd given him on the hill with her spear raised.
"Thought you'd never ask," she said.
[FAITH: Clarisse La Rue's faith in the Host has deepened. +200 Faith.]
[Note: The Host has given a gift greater than strength.]
Clarisse went up to the attic of the Big House alone, at noon.
The whole camp waited on the lawn outside. Nobody talked. Percy sat on the porch steps with his chin in his hands and listened to the creak of the old floorboards over his head. And then the silence.
And then the green.
It came out of the attic window in a thick, coiling plume. Green smoke, like the smoke that had poured out of Rachel's mouth on a rooftop in October. It curled down over the porch and the lawn, and it smelled of old snakes and laurel leaves and the cracks in the earth at Delphi. Everybody on the lawn shivered. Percy shivered too, for a different reason.
She is not yet mine, the voice on the rooftop had said. But soon.
When Clarisse came back down the stairs, she was pale and shaking. She stopped at the top of the porch steps and looked out at the camp. Then she said it, in a flat, careful voice, like she was reading it off a piece of paper inside her head.
"The child of war shall cross the sea of night,
With the starborn's son and the vine-born to fight.
The goat in the cave shall be freed from his bride,
But the fleece will cost blood on the water's dark tide.
And one shall return on the wings of a storm,
Who carries the gold home, but not his own form."
Nobody said anything.
Percy sat on the porch steps and went over it in his head, line by line, with the cold sinking feeling of someone reading a prophecy he didn't recognize.
It was different. Completely different from the one in his first life. The child of war, that was Clarisse. The goat in the cave, that was Grover. The fleece costing blood, that was bad.
The starborn's son. That one he didn't know.
The vine-born. A child of Dionysus.
And the last line. One shall return on the wings of a storm, who carries the gold home, but not his own form.
He didn't understand that one at all. And he didn't like it.
[ORACULAR PROPHECY RECORDED.]
[Great Sage notes: This prophecy diverges significantly from the Host's previous timeline.]
[Great Sage notes: The phrase "not his own form" carries multiple interpretations. Several of them are concerning.]
Yeah, Percy thought grimly. I noticed.
"The starborn's son," Odysseus said thoughtfully. He was leaning on the porch railing, looking out at the camp. "Starborn. Hmm." His clever eyes slid sideways. "There's a shadow at this camp, I'm told, whose name means the starry one. Asterion. Isn't there? And a boy who gave it back to him." He looked at Percy. "I'd say that makes you the starborn's... well. Not son, exactly. But near enough, for an Oracle. They're never precise."
Percy stared at him.
"Or it's a son of Zeus," said Perseus helpfully, from where he was hovering about six feet off the porch in his winged sandals. "Zeus. Sky. Stars. Starborn." He grinned. "Could be me, honestly. Or you, little brother. Probably you. I'm dead."
"And the vine-born," said Dionysus, from his lawn chair on the porch.
His voice had changed.
He wasn't slouched anymore. He was sitting up straight, with his Diet Coke forgotten in his hand, and his purple eyes were fixed on the two boys standing together at the edge of the crowd. Castor and Pollux. His sons. The twins.
"A child of mine," said the god of wine quietly. "On a quest. To the Sea of Monsters." He looked at the prophecy hanging in the air like smoke. The fleece will cost blood on the water's dark tide. "Absolutely not."
"Dad—" Castor started.
"No."
"Dad," said Castor again. He stepped forward, out of the crowd, and his brother stepped with him. They were both tall and lanky and curly-haired, with their father's purple-tinged eyes, and they'd never once in their lives looked anything but bored. They didn't look bored now. "It's a prophecy. It says the vine-born. It has to be one of us."
"It doesn't have to be anything," snapped Dionysus. "Prophecies are vague. They're always vague. It could mean a dryad. It could mean a grape. It could mean anyone who's ever had a glass of wine!" His eyes were glowing now. "I am not sending my sons to the Sea of Monsters to bleed on some tide—"
"I'll go," said Castor.
The god of wine stopped.
Castor stood very straight in front of his father's lawn chair, with his chin up. He was shaking. But he didn't back down.
"I'll go," he said again. "Pollux stays. I go. That way, if..." He swallowed. "If something happens, you'll still have one of us."
Pollux made a sound like he'd been punched. He grabbed his brother's arm. "No, I'll go—"
"I'm older," said Castor. "By four minutes. I go."
Dionysus stared at his son.
For a long moment, the god of wine didn't say anything at all. His purple eyes were blazing. His knuckles were white around his soda can. And then, slowly, his gaze moved from Castor to Percy.
And Percy understood, all at once, what the god was asking him. Without words. Without anything but those burning purple eyes.
In his first life, Castor had died. In the Battle of the Labyrinth. A year from now, in that other world. Speared in the chest by a monster in the woods behind camp, defending the cabins. Pollux had cried over his body for an hour. And Dionysus had never said a word about it to anyone, ever. But he'd never been the same.
Not this time, Percy thought.
"I'll bring him back," he said. Out loud. To the god of wine. In front of the whole camp. "Whatever happens. Whatever the prophecy says. Castor comes home."
Dionysus looked at him for a long, long time.
"You swear it?" he said finally. Very quietly. "Not on the Styx. You're collecting too many of those. Just... you swear it?"
"I swear it," said Percy.
The god of wine closed his eyes.
Then he slumped back in his lawn chair, and picked up his Diet Coke, and took a long drink. And when he spoke again his voice was its normal bored, irritable drawl. Almost.
"Fine," said Dionysus. "Go. All of you. Get out of my sight." He waved his hand. "And Peter Johnson?"
"Yeah?"
"If my son comes back with so much as a scratch on him," said the god of wine, "I will turn you into a dolphin. And not a nice dolphin. A sad dolphin."
"Understood, sir."
[QUEST ACCEPTED: THE SEA OF MONSTERS.]
[Leader: Clarisse La Rue. Companions: Perseus Jackson, Castor (son of Dionysus).]
[Objectives: Retrieve the Golden Fleece. Rescue Grover Underwood. Return before the boundary fails.]
[Time limit: 9 days.]
[SIDE QUEST (Personal): THE VINE-BORN. Bring Castor home alive.]
[Note: A promise made to a god before witnesses carries weight.]
And under that, smaller, in a color Percy had never seen the System use before. A deep, rich, ocean blue.
[BLOODLINE THREAD II: THE SEA.]
[The Host's second bloodline stirs. It is waiting at the bottom of the world's deepest water.]
[Awakening condition: ???]
Percy read that line three times.
Then he looked up, across the camp, past the cabins and the fields and the canoe lake, toward the Sound.
The sea was glittering in the noon sun. Blue and endless.
And for just a second, so faint he might have imagined it, he thought he heard it say his name.
