He saw the smoke from ten miles out.
A black column of it, rising from the North Shore of Long Island into the clear June sky, bending east in the wind. Rime saw it too. The shadow dragon let out a low, cold hiss and put on speed, its frost-edged wings beating so hard the air froze into glittering crystals behind them.
Percy lay flat against its neck with his arms wrapped around it and his eyes streaming in the wind. He was so tired he could barely hold on. The shadow-sickness from the long jump to Manhattan was still twisting his stomach. Every minute in the air, he could feel his life draining out of him and into the dragon, like water through a crack in a cup.
[HP: 1,410 / 3,040.]
[MP: 140 / 760. (Regenerating.)]
[Status: SHADOW-SICK. Remaining: 1 hour, 12 minutes.]
[Time until boundary collapse: 9 minutes.]
Faster, he thought at Rime. Please. Faster.
The dragon screamed, and dove.
Camp Half-Blood came up out of the green hills like a wound.
The strawberry fields were burning. Half the fields, a great black scar of smoldering plants and smoke spreading across the valley. The roof of the Hermes cabin was on fire. The climbing wall had toppled over sideways, still pouring lava down one side, and the lava was running across the grass toward the canoe lake in a slow, steaming river.
And at the top of Half-Blood Hill, where Thalia's pine stood, the boundary was failing.
Percy could see it. Mist-Sight let him see the magic, the way it always did. The great golden dome of the camp's protection, usually so strong and steady it hummed like a power line. It was flickering. Guttering. Holes were opening in it and closing and opening again, like a candle flame in a draft. And the pine itself, at the center of it all, the tree that had once been a girl, was dying. Its needles had gone yellow. Its bark was weeping a thick, black, oily sap. It looked like it was rotting from the inside out.
And on the slope of the hill below it, the camp was fighting for its life.
There were two bulls. Huge things, bigger than elephants, made of shining bronze. Their eyes were glowing coals and their nostrils were blasting jets of white fire twenty feet long. They were charging up and down the slope of the hill, trampling and burning everything they touched. Every time they hit the flickering boundary, the dome of gold light shuddered, and another hole tore open in it.
And there were cyclopes.
Four of them. Huge, shaggy, filthy creatures with single bloodshot eyes in the middle of their foreheads, wearing rags and carrying clubs made of whole tree trunks. They were coming up the hill from the road on the far side, through the gaps in the boundary as it flickered, roaring. Behind them, further down the road, Percy could see more shapes coming. Hellhounds. Dracaenae. Something big with too many heads.
And between the monsters and the camp was a thin line of demigods.
The Ares cabin, in front, in full armor, with spears and shields locked together in a wall, holding the slope. Clarisse in the middle of them, screaming orders, her electric spear crackling. Behind them, the Apollo archers on the roof of the Big House, firing arrow after arrow down into the bulls. They might as well have been firing at a tank. Kids from Hephaestus and Athena and Demeter, dragging buckets of water from the canoe lake. Trying to put out the fires and losing.
And Chiron. In his full centaur form, galloping back and forth across the slope behind the shield wall with his bow in his hands. Firing and firing and firing. His face grim and gray.
They were losing. Percy could see it in a single glance. Strategist's Eye spread the whole battle out in front of him like a chessboard, every piece, every move. And the board was going one way. Too many monsters. Too few demigods. A boundary that was falling apart. Two bronze bulls nobody could hurt.
[STRATEGIST'S EYE: Battlefield analysis.]
[Projected outcome without intervention: Boundary collapse in 7 minutes. Camp overrun in 19.]
[Projected camper casualties: Unacceptable.]
Not today, Percy thought.
He sat up on Rime's back, in the wind, over the burning camp.
And he called his army.
The shadows came down out of the sky like rain.
They poured off of Rime's wings in a great black flood and hit the slope of Half-Blood Hill one after another, between the shield wall and the monsters, and stood up.
Asterion first. The Minotaur's shadow, eight feet tall and horned and terrible, with his double-headed axe of living darkness. Then Gorrath, the Orc King, roaring, his great cleaver raised. Fang, the shadow lycan, howling, with four lesser shadow wolves boiling up out of the ground around him. Chi-Chi, the Chimera, her lion's head roaring fire and her serpent tail hissing. Lazarus, the Necromancer, tall and thin and cloaked, already raising his hands, and the bones of a thousand years of dead monsters beginning to stir in the dirt of the hill. Gloop, the Slime King, splitting into a dozen smaller slimes that went bouncing off down the slope at the cyclopes' ankles. Thing One and Thing Two, with their flail and their tower shield, planting themselves at the gaps in the boundary.
And Hammer and Anvil. The two shadow giants, nine feet tall, with dark fire burning in their huge hands.
The whole battle stopped.
For one long second, nobody moved. Not the monsters. Not the demigods. Every face on that hill turned to look at the ten shadows standing in a line between the camp and the enemy, silent and dark and enormous. And then looked up, at the dragon circling overhead, with a boy on its back.
"Is that—" somebody in the shield wall shouted.
"IT'S PERCY!" screamed Marcus, the little unclaimed kid from Cabin Eleven, from the roof of the dining pavilion. "PERCY'S HERE! PERCY BROUGHT A DRAGON!"
And the camp roared.
It was the loudest sound Percy had ever heard. A hundred demigods, all yelling at once, from every corner of the burning valley. It went up into the smoke-black sky like a wave. And Percy felt something hit him like a punch to the chest. Warm and bright and fierce. Pouring into him from every direction, from every voice.
Faith.
[FAITH: The campers of Camp Half-Blood believe in the Host.]
[+800 Faith.]
[+1,100 Faith.]
[+1,400 Faith.]
Not now, he thought, dazed. Later. Fight first.
He leaned down over Rime's neck.
"Asterion! Gorrath! The cyclopes!" he shouted. "Hammer, Anvil, hold the gaps! Lazarus, get me bodies on that road, slow down whatever's coming up behind them! Fang, Chi-Chi, flank them! Thing One, Thing Two, protect the tree!"
The shadows moved.
And Percy turned Rime toward the bulls.
The bulls were the problem.
The Colchis bulls. Forged by Hephaestus himself, a gift to a king, thousands of years ago. Solid bronze, all the way through. Arrows bounced off them. Spears broke on them. They didn't get tired. They didn't feel pain. And every time they breathed, they set something else on fire.
Percy had fought them before, in his first life. On this same hill. He'd been rescued by a Cyclops who couldn't be burned, while the bulls breathed fire over both of them.
This time, he had a dragon made of ice.
Rime dove at the first bull like a falling glacier. Its breath hit the bronze monster's back in a torrent of white frost. And the bull, which had been red-hot from the inside from all its fire-breathing, screamed. A horrible metallic shriek. Steam exploded off it in a great white cloud. The bronze cracked, all along its spine, with a sound like a church bell breaking.
The bull staggered. It turned. It breathed fire straight up at the dragon.
The fire hit Rime's wing, and the shadow-ice hissed and melted, and the dragon lurched sideways in the air. Percy nearly fell off. He grabbed for its neck and missed. He was sliding, falling, there was nothing under him but smoke and burning grass forty feet below—
[MARGIT'S CLOAK: Lethal fall detected. Decoy deployed.]
He blinked three feet to the side, and landed on the slope of the hill in a roll. He came up on one knee in the burning grass with the breath knocked out of him.
Right in front of the second bull.
It looked at him with its coal-red eyes. And it breathed.
White fire, at point-blank range, like being hit with the inside of a furnace. Percy threw his arm up—
[PROTEUS: Realm of the Ward. Form: Banished Knight's Greatshield.]
—and the fire hit the shield and broke around it, pouring past him on both sides. The grass at his feet burst into flames. The heat was unbelievable. His eyebrows singed off. His hair started to smoke.
And then something strange happened.
He started to feel better.
[HEARTHKEEPER: The Host is near flame.]
[HP and Stamina regeneration x3.]
[HEAT-SKIN: Fire damage resisted.]
Percy stared at the fire roaring around him, at the burning grass, at the bronze bull breathing white flame at him from ten feet away.
And he started to laugh.
"Hestia," he gasped. "Hephaestus. Thank you."
He stood up. Right there, in the middle of the fire. With his shield up and the flames pouring around him, healing him, faster than they could burn him.
[HP: 1,410 → 1,890 → 2,270.]
The bull stopped breathing fire. It stood there, confused, staring at the smoking boy who should have been a pile of ash by now.
Percy let the shield melt back into a sword.
[PROTEUS: Realm of the Fist. Form: The Dragon-Headed Fist.]
And then not a sword. A gauntlet, heavy and scaled and shaped like the head of a dragon, wrapped around his right hand and forearm.
"Your turn," he told the bull. And he punched it in the face.
The gauntlet roared. A cone of fire blasted out of the dragon's mouth on his fist and hit the bull square between the eyes. It wasn't the white fire of the bull's own breath. It was red and orange and gold, the fire of Godrick's grafted dragon, scaling with every point of Percy's strength and every drop of faith pouring into him from the hillside. The bull's bronze face melted. It went soft and runny like wax. The coal-red eyes went out. The bull reared back, screaming, its face a dripping, glowing ruin.
And behind it, on the far side of the hill, the boundary flickered.
[Time until boundary collapse: 3 minutes.]
That was when the taxi arrived.
Percy heard it before he saw it. A horrible screech of tires, and three old women screaming at each other in loud, cracked voices about whose turn it was with the eye. Then a battered gray car came tearing up the road from the highway, straight through the middle of the monster army. It flattened two hellhounds and a dracaena. It fishtailed to a stop at the bottom of the hill in a spray of gravel.
The back doors flew open.
Tyson came out first.
He was huge. Even huger than he'd looked in the gym. And when he saw the burning hill and the bronze bull and the cyclopes, his face crumpled with distress.
"No!" he bellowed. "Bad cows! BAD!"
And he charged straight up the slope at the first bull. The one Rime had frozen, the one with the cracked spine. It breathed fire at him. Tyson ran straight through the fire like it was a light rain. His clothes burned away, but his skin didn't. He grabbed the bull by both horns and heaved.
The bull went over on its side with a crash that shook the hill. Tyson sat on it.
"Stay!" he roared. "Stay, cow! Bad!"
The bull thrashed and screamed and blasted fire into the sky. Tyson didn't budge.
Annabeth came out of the taxi next, with her knife drawn. She took one look at the battle, at the flickering boundary, at the shadows and the cyclopes and the shield wall. And without a word she sprinted up the hill toward the Ares cabin. She shouted something at Clarisse that Percy couldn't hear. Clarisse's head whipped around. A second later, the whole shield wall shifted, pivoted, swung around to flank the nearest cyclops, exactly the way Strategist's Eye had been showing Percy it should.
And then Ezra came out of the taxi.
He stood at the bottom of the hill for one second, looking up at it all. The fire. The smoke. The dying tree. The bull with its melted face, rearing up over Percy.
Then he looked at the canoe lake.
It was half a mile away, at the bottom of the valley. Too far. Way too far. Even Ezra couldn't pull water that far.
He didn't try to.
He dropped to one knee on the gravel road. He put both hands flat on the ground. And he closed his eyes, and listened. Not to the lake. To what was underneath it. Under the whole valley. Under the hill. The water that ran through the rock and the dirt and the roots, deep down, in the dark, where nobody could see it.
The ground under the burning hill heaved.
And the springs burst up.
A dozen of them, all at once, all across the slope of Half-Blood Hill. Great white geysers of cold water exploding up out of the earth, twenty, thirty, forty feet into the air. They came down on the burning grass and the burning strawberry fields and the burning roof of the Hermes cabin like a monsoon. The fires went out with a scream of steam. The lava from the climbing wall hissed and hardened into black rock.
And one geyser, the biggest of all, burst up directly underneath the second bull. The one with the melted face, rearing over Percy.
It hit the red-hot bronze from below. And the bull exploded.
Not in fire. In steam. A huge, white, scalding, screaming cloud of it, as the cold water hit the white-hot metal from the inside. The bronze cracked and split and burst apart into a hundred glowing pieces. They rained down across the hillside, hissing, smoking, harmless.
Percy stood in the middle of the steam, soaking wet, with the Dragon-Headed Fist still smoking on his arm. He looked down the hill.
Ezra was still kneeling on the gravel road with his hands on the ground. He looked up at Percy, through the steam and the falling water.
And he grinned.
"Told you," he called up the hill. "I'm catching up."
After that, it was a rout.
The cyclopes broke first. They'd seen the bull explode. They'd seen the shadow army. They'd seen a dragon made of ice. And now there was a boy who could pull rivers out of the ground, and a second Cyclops, a small one, sitting on the other bull and telling it it was bad. One of them turned and ran. Asterion caught it before it got ten feet. Gorrath and Fang and Chi-Chi got the second. The Ares cabin got the third, Clarisse's electric spear in its one eye. Hammer and Anvil got the fourth, with a volley of dark fire that lit up the whole hillside.
And the army behind them, the hellhounds and dracaenae and the thing with too many heads, came up the road and found Lazarus waiting. With three hundred skeletons of dead monsters, risen out of the dirt of a hill where demigods had been fighting monsters for a hundred years. They didn't even make it to the bottom of the slope.
Tyson's bull was the last.
It lay on its side on the hill, thrashing and screaming, with Tyson sitting on it and patting its bronze head, and saying "Shh, shh, it's okay, bad cow, it's okay." It couldn't get up. But it couldn't be killed either. Not by spears, not by arrows.
Percy walked over to it.
He looked down at the bronze bull. At its coal-red eyes, glaring up at him with mindless rage. At the cracked spine where Rime had frozen it.
Then he looked at Tyson.
"Can you hold it still?" he said. "Just for a second?"
Tyson nodded solemnly. He wrapped both huge arms around the bull's neck and squeezed.
Percy held out his hand.
[PROTEUS: Realm of the Heavens. Form: The Unclaimed Bolt.]
He drove the bolt down into the crack in the bull's spine.
The lightning went through the bronze like it was water. Every circuit, every gear, every enchanted rune that Hephaestus had carved into it three thousand years ago lit up blue-white from the inside, all at once. And the Colchis bull went still.
[ENEMIES DEFEATED: Colchis Bulls (x2). Cyclopes (x4). Monster vanguard (x31).]
[EMERGENCY QUEST: THE HILL BURNS — COMPLETE.]
[The camp did not fall.]
[+180,000 EXP.]
[LEVEL UP! Level 91 → Level 94.]
The hill was very quiet.
Smoke drifted across it in long gray curtains. Water was still trickling down the slope from Ezra's geysers, in little streams, between the bodies of monsters crumbling into gold. Somebody, somewhere, was crying. Somebody else was laughing, the shaky, breathless laughter of someone who couldn't believe they were still alive.
Percy stood in the middle of it all, with his clothes burned to rags and his hair singed and his whole body shaking, and looked around.
At the shield wall, still standing, battered and burned. At Clarisse, leaning on her spear, bleeding from a cut on her forehead, grinning at him like a lunatic. At Annabeth, sitting in the wet grass with her knife in her lap, staring at the shadows. At Tyson, still sitting on the dead bull, patting its head sadly. At Chiron, standing at the top of the hill under the dying pine, his bow lowered, his face unreadable.
At Ezra. Walking slowly up the slope toward him, soaking wet, with Riptide in his hand and a look on his face like he'd just found out he could fly.
And at the hundred demigods of Camp Half-Blood, coming out from behind walls and up from buckets and down from rooftops. Standing all over the burned, wet, smoking hillside. Looking at him.
Nobody said anything.
Then Clarisse La Rue lifted her spear, high, over her head.
And the Ares cabin lifted their spears with her.
And then the Apollo archers lifted their bows. And the Hephaestus kids lifted their hammers. And the Demeter kids lifted their shovels, and the Athena kids lifted their swords, and the Hermes kids and the unclaimed kids from Cabin Eleven lifted whatever they had. Spoons and buckets and rakes and bare fists. All over the hill. All at once. In silence.
Percy stood there, in the middle of it, and didn't know what to do with his face.
[FAITH: Camp Half-Blood has witnessed the Host defend it.]
[+2,300 Faith.]
[VESSEL RANK-UP CONDITIONS MET.]
[The Host is not at rest. Rank-up deferred.]
[...Override. Great Sage has decided the Host has earned it now.]
[VESSEL RANK: D → C.]
It hit him like a wave of warm water. Rolling up from his feet, through his chest, out to the tips of his fingers. He felt his body change. Stronger. Faster. Clearer. The exhaustion lifted off of him like a coat. The shadow-sickness vanished. The burns on his skin faded.
And the darkness inside him, where his shadows lived, opened up. Like a room he'd been living in had suddenly grown new walls, and new windows, and a high, wide ceiling, full of empty space.
[VESSEL RANK: C.]
[All stats +8.]
[Shadow Army capacity: 13 → 21 (20 + 1 Bound Slot).]
[HP and MP fully restored.]
[Faith toward Rank B: 1,810 / 20,000.]
[Great Sage notes: Great Sage is aware that it is not supposed to override rank timing. Great Sage did it anyway. Great Sage considers this a growth experience.]
Percy laughed out loud, standing on the hill. Half the camp looked at him like he'd lost his mind.
Thanks, he thought.
[Great Sage will remain here.]
There was golden dust all over Half-Blood Hill. Four big piles, where the cyclopes had fallen. And two great heaps of shattered, smoking bronze, where the bulls had been.
Percy looked at them for a long time.
Twenty-one, he thought. I'm at eleven.
The cyclopes were Kronos's soldiers. Sent to burn the camp, and kill everyone in it. If he left them, they'd re-form in Tartarus eventually and come back for another try.
The bulls were Hephaestus's. Forged by the god of the forge himself. Stolen, probably. Twisted, and sent against the god's own children's camp.
Not anymore, he thought.
He walked down the slope to the nearest pile of golden dust. He held out his hand.
"Arise," said Percy Jackson.
The darkness came up out of the hill like smoke from a dying fire. Four times, out of the four piles of golden dust. And it rose into four enormous shapes, shaggy and one-eyed, kneeling on the burned grass of Half-Blood Hill with their heads bowed.
Then twice more, out of the shattered bronze. The pieces of the bulls lifted themselves off the ground, and spun together in the air, and fused. Their dull bronze turned to shining black. Their coal-red eyes turned to cold blue stars. And they stood, two great bulls of living shadow and dark bronze, and lowered their horns before him. Fire was dripping like water from their nostrils, the same cold blue as Rime's eyes.
[Shadow Extraction successful (x6).]
[New Shadows: SHADOW CYCLOPS (x4). Rank: KNIGHT. Ability retained: Forge Strength, Boulder Throw.]
[New Shadows: COLCHIS BULL (x2). Rank: ELITE. Ability retained: Breath of the Forge (shadowflame), Bronze Hide.]
[Name your shadows.]
Percy looked at the four kneeling cyclopes. Huge and shaggy and gentle-eyed now, in shadow form.
"Boulder," he said. "Crag. Flint. Slate."
He looked at the two bulls.
"Bellows," he said. "And Brass."
[Shadow Army: 17 / 21.]
The hill was dead silent.
A hundred demigods were staring at him. At the six new shadows kneeling at his feet, beside the eleven already standing behind him. Seventeen shadows. An army. On a burned hill, under a dying tree, in the smoke.
And from the top of the hill, beneath Thalia's pine, Chiron was watching him. The old centaur hadn't moved. His bow was still lowered. His face was still unreadable.
But there was something in his ancient eyes Percy had never seen there before, in either life.
It might have been awe.
It might have been fear.
It might have been both.
Tyson broke the silence.
He'd climbed down off the place where his bull had been, and he was standing in the burned grass, staring at the two new shadow bulls with his mouth open and his one huge brown eye wide with wonder.
"Pretty cows," he whispered. "Good cows now."
One of the shadow bulls, Bellows, turned its great dark head and looked at him. Then it walked over, very slowly, and lowered its head, and bumped its nose gently against Tyson's chest.
Tyson started to cry. Happy tears.
And for some reason, that was what finally did it. Percy sat down in the wet burned grass of Half-Blood Hill, in the middle of his army, with his face in his hands, and laughed until his ribs hurt.
When he looked up, Ezra was sitting next to him. And Annabeth. And Clarisse, still grinning, still bleeding. And Tyson, with a shadow bull leaning against him like a giant dog.
Nobody said anything.
Behind them, at the top of the hill, Thalia's pine creaked in the wind. Its needles were yellow. Black sap was weeping from its bark like tears.
The boundary was still flickering.
The fight was over.
The war wasn't.
