Chapter 1

Percy,

The whole world had become chaos. Kronos had lifted Morpheus' sleeping spell. All the mortals had awakened and were running around screaming unable to believe the sight before them. My Mom and Step Dad, Paul awoke in their Prius got out and looked straight at me. I motioned for them to leave but they came toward me as she could see through the Mist and knew what was going on.

As a snake monster came toward them, Paul picked up a sword and engaged the dracaena in combat and with a few fancy moves killed her. I watched amazed, saying, "Paul"?

He turned toward me and grinned. "I hope that was a monster I just killed. I was a Shakespearian actor in college! Picked up a little swordplay!"

I liked him even better for that, but then a Laistrygonian giant charged toward my mom. She was rummaging around in an abandoned police car-maybe looking for the emergency radio-and her back was turned.

"Mom!" I yelled.

She whirled when the monster was almost on top of her. I thought the thing in her hands was an umbrella until she cranked the pump and the shotgun blast blew the giant twenty feet backward, right into Nico's sword.

"Nice one," Paul said.

"When did you learn to fire a shotgun?" I demanded.

My mom blew the hair out of her face. "About two seconds ago. Percy, we'll be fine. Go!"

"Yes," Nico agreed, "we'll handle the army. You have to get Kronos!"

"Come on, Seaweed Brain!" Annabeth said. I nodded. Then I looked at the rubble pile on the side of the build ing. My heart twisted. I'd forgotten about Chiron. How could I do that?

"Mrs. O'Leary," I said. "Please, Chiron's under there. If anyone can dig him out, you can. Find him! Help him!"

I'm not sure how much she understood, but she bounded to the pile and started to dig. Annabeth, Thalia, Grover, and I raced for the elevators.

Line Break

Kronos had already reached Olympus as was evident from the damage. The connection with the mortal world was fading and as soon as we stepped off the elevator the bridge started to crack.

"Let's go", I said. We all raced across the bridge in the nick of time. I looked at the damage caused by Kronos. Torn and broken armor and weapons littered the ground along with immortal dust. Probably the leftovers of the few brave demigods and minor gods and goddesses who tried to stop Kronos.

We followed the winding path toward the palace of the gods. I didn't remember the road being so long. Maybe Kronos was making time go slower, or maybe it was just dread slowing me down. The whole mountaintop was in ruins-so many beautiful buildings and gardens gone.

Suddenly, a huge spout of water blasted into the sky. "Damn it", I said that was one of my dad's fountains. A second later the whole mountain shook and huge statues of the King and Queen of the Gods fell right toward us.

"Watch out", yelled Thalia and pushed us out of the way, as the statue fell on her, pinning her.

We tried desperately to move it, but it would've taken several Cyclopes. When we tried to pull Thalia out from under it, she yelled in pain.

"I survive all those battles," she growled, "and I get defeated by a stupid chunk of rock!"

"It's Hera," Annabeth said in outrage. "She's had it in for me all year. Her statue would've killed me if you hadn't pushed us away."

Thalia grimaced. "Well, don't just stand there! I'll be fine. Go!"

We didn't want to leave her, but I could hear Kronos laughing as he approached the hall of the gods. More build ings exploded.

"We'll be back," I promised.

"I'm not going anywhere," Thalia groaned.

A fireball erupted on the side of the mountain, right near the gates of the palace.

"We've got to run," I said.

"I don't suppose you mean away," Grover murmured hopefully.

I sprinted toward the palace, Annabeth right behind me.

"I was afraid of that," Grover sighed, and clip-clopped after us.

The doors of the palace were big enough to steer a cruise ship through, but they'd been ripped off their hinges and smashed like they weighed nothing. We had to climb over a huge pile of broken stone and twisted metal to get inside.

Kronos stood in the middle of the throne room, his arms wide, staring at the starry ceiling as if taking it all in. His laughter echoed even louder than it had from the pit of Tartarus.

"Finally!" he bellowed. "The Olympian Council-so proud and mighty. Which seat of power shall I destroy first?"

Ethan Nakamura stood to one side, trying to stay out of the way of his master's scythe. The hearth was almost dead, just a few coals glowing deep in the ashes. Hestia was nowhere to be seen. Neither was Rachel. I hoped she was okay, but I'd seen so much destruction I was afraid to think about it. The Ophiotaurus swam in his water sphere in the far corner of the room, wisely not making a sound, but it wouldn't be long before Kronos noticed him.

Annabeth, Grover, and I stepped forward into the torch light. Ethan saw us first.

"My lord," he warned.

Kronos turned and smiled through Luke's face. Except for the golden eyes, he looked just the same as he had four years ago when he'd welcomed me into the Hermes cabin. Annabeth made a painful sound in the back of her throat, like someone had just sucker punched her.

"Shall I destroy you first, Jackson?" Kronos asked. "Is that the choice you will make-to fight me and die instead of bowing down? Prophecies never end well, you know."

"Luke would fight with a sword," I said. "But I suppose you don't have his skill."

Kronos sneered. His scythe began to change, until he held Luke's old weapon, Backbiter, with its half-steel, half-Celestial bronze blade.

Next to me, Annabeth gasped like she'd suddenly had an idea. "Percy, the blade!" She unsheathed her knife. "The hero's soul, cursed blade shall reap."

I didn't understand why she was reminding me of that prophecy line right now. It wasn't exactly a morale booster, but before I could say anything, Kronos raised his sword.

"Wait!" Annabeth yelled.

Kronos came at me like a whirlwind.

My instincts took over. I dodged and slashed and rolled, but I felt like I was fighting a hundred swordsmen. Ethan ducked to one side, trying to get behind me until Annabeth intercepted him. They started to fight, but I couldn't focus on how she was doing. I was vaguely aware of Grover playing his reed pipes. The sound filled me with warmth and courage-thoughts of sunlight and a blue sky and a calm meadow, somewhere far away from the war.

Kronos backed me up against the throne of Hephaestus-a huge mechanical La-Z-Boy type thing covered with bronze and silver gears. Kronos slashed, and I managed to jump straight up onto the seat. The throne whirred and hummed with secret mechanisms. Defense mode, it warned. Defense mode.

That couldn't be good. I jumped straight over Kronos's head as the throne shot tendrils of electricity in all directions. One hit Kronos in the face, arcing down his body and up his sword.

"ARG!" He crumpled to his knees and dropped Backbiter.

Annabeth saw her chance. She kicked Ethan out of the way and charged Kronos. "Luke, listen!"

I wanted to shout at her, to tell her she was crazy for trying to reason with Kronos, but there was no time. Kronos flicked his hand. Annabeth flew backward, slamming into the throne of her mother and crumpling to the floor.

"Annabeth!" I screamed.

Ethan Nakamura got to his feet. He now stood between Annabeth and me. I couldn't fight him without turning my back on Kronos.

Grover's music took on a more urgent tune. He moved toward Annabeth, but he couldn't go any faster and keep up the song. Grass grew on the floor of the throne room. Tiny roots crept up between the cracks of the marble stones.

Kronos rose to one knee. His hair smoldered. His face was covered with electrical burns. He reached for his sword, but this time it didn't fly into his hands.

"Nakamura!" he groaned. "Time to prove yourself. You know Jackson's secret weakness. Kill him, and you will have rewards beyond measure."

Ethan's eyes dropped to my midsection, and I was sure that he knew. Even if he couldn't kill me himself, all he had to do was tell Kronos. There was no way I could defend myself forever.

"Look around you, Ethan," I said. "The end of the world. Is this the reward you want? Do you really want everything destroyed-the good with the bad? Everything?"

Grover was almost to Annabeth now. The grass thickened on the floor. The roots were almost a foot long, like a stubble of whiskers.

"There is no throne to Nemesis," Ethan muttered. "No throne to my mother."

"That's right!" Kronos tried to get up, but stumbled. Above his left ear, a patch of blond hair still smoldered. "Strike them down! They deserve to suffer."

"You said your mom is the goddess of balance," I reminded him. "The minor gods deserve better, Ethan, but total destruction isn't balance. Kronos doesn't build. He only destroys."

Ethan looked at the sizzling throne of Hephaestus. Grover's music kept playing, and Ethan swayed to it, as if the song were filling him with nostalgia-a wish to see a beautiful day, to be anywhere but here. His good eye blinked.

Then he charged . . . but not at me.

While Kronos was still on his knees, Ethan brought down his sword on the Titan lord's neck. It should have killed him instantly, but the blade shattered. Ethan fell back, grasping his stomach. A shard of his own blade had ricocheted and pierced his armor.

Kronos rose unsteadily, towering over his servant. "Treason," he snarled.

Grover's music kept playing, and grass grew around Ethan's body. Ethan stared at me, his face tight with pain.

"Deserve better," he gasped. "If they just . . . had thrones-"

Kronos stomped his foot, and the floor ruptured around Ethan Nakamura. The son of Nemesis fell through a fissure that went straight through the heart of the mountain-straight into open air.

"So much for him." Kronos picked up his sword. "And now for the rest of you."

My only thought was to keep him away from Annabeth.

Grover was at her side now. He'd stopped playing and was feeding her ambrosia.

Everywhere Kronos stepped, the roots wrapped around his feet, but Grover had stopped his magic too early. The roots weren't thick or strong enough to do much more than annoy the Titan.

We fought through the hearth, kicking up coals and sparks. Kronos slashed an armrest off the throne of Ares, which was okay by me, but then he backed me up to my dad's throne.

"Oh, yes," Kronos said. "This one will make fine kindling for my new hearth!"

I knew I was not as strong as a Titan, but for the moment I felt the power of the ocean in my arms. I slashed at him with all my might and he swung at me to block my strike. As soon as the two blades struck each other, I had a bad feeling. The point of intersection of the two blades was where it happened. A ball of pure white light formed there, getting larger and larger as a cracking sound filled the air. I finally realized what it was, the immortal power of the Hesperides, my friend Zoe to be exact.

It was doing its best to stop Backbiter from cracking it but I realized it was futile. The sword started to crack and then Riptide cracked into a million pieces as a huge explosion occurred throwing Kronos across the throne room and against the white wall, creating a large depression which made his blade slip through his fingers and fall into the roaring hearth.

A white ball of light arose and stopped in front of me as if asking me where to go.

I thought of Zoe, my friend, the huntress, and everything I knew about her. I remembered my dreams, her last words and as if the immortal ball of power read my mind, it nodded and left. I quickly got up and saw Kronos trying to get his blade. But, the hearth burned his hand black as Hestia shook her hand at him as if he was a naughty boy and he couldn't retrieve it.

"A minor setback" he proclaimed and laughed, "Poor Perseus Jackson, your toothpick is gone, how are you going to stop me now."

He stamped his foot again and time slowed. I tried to attack but I was moving at the speed of a glacier. Kronos backed up leisurely, catching his breath. I struggled forward, silently cursing him. He could take all the time-outs he wanted. He could freeze me in place at will. My only hope was that the effort was draining him. If I could wear him down . . .

"It's too late, Percy Jackson, even though you have taken away my weapon." he said. "Behold."

He pointed to the hearth, and the coals glowed. A sheet of white smoke poured from the fire, forming images like an Iris-message. I saw Nico and my parents down on Fifth Avenue, fighting a hopeless battle, ringed in enemies. In the background Hades fought from his black chariot, summon ing wave after wave of zombies out of the ground, but the forces of the Titan's army seemed just as endless. Meanwhile, Manhattan was being destroyed. Mortals, now fully awake, were running in terror. Cars swerved and crashed.

The scene shifted, and I saw something even more terrifying.

A column of storm was approaching the Hudson River, moving rapidly over the Jersey shore. Chariots circled it, locked in combat with the creature in the cloud.

The gods attacked. Lightning flashed. Arrows of gold and silver streaked into the cloud like rocket tracers and exploded. Slowly, the cloud ripped apart, and I saw Typhon clearly for the first time.

I knew as long as I lived (which might not be that long) I would never be able to get the image out of my mind. Typhon's head shifted constantly. Every moment he was a different monster, each more horrible than the last. Looking at his face would've driven me insane, so I focused on his body, which wasn't much better. He was humanoid, but his skin reminded me of a meat loaf sandwich that had been in someone's locker all year. He was mottled green, with blisters the size of buildings, and blackened patches from eons of being stuck under a volcano. His hands were human, but with talons like an eagle's. His legs were scaly and reptilian.

"The Olympians are giving their final effort." Kronos laughed. "How pathetic."

Zeus threw a thunderbolt from his chariot. The blast lit up the world. I could feel the shock even here on Olympus, but when the dust cleared, Typhon was still standing. He staggered a bit, with a smoking crater on top of his misshapen head, but he roared in anger and kept advancing.

My limbs began to loosen up. Kronos didn't seem to notice. His attention was focused on the fight and his final victory. If I could hold out a few more seconds, and if my dad kept his word . . .

Typhon stepped into the Hudson River and barely sank to midcalf.

Now, I thought, imploring the image in the smoke. Please, it has to happen now.

Like a miracle, a conch horn sounded from the smoky picture. The call of the ocean. The call of Poseidon.

All around Typhon, the Hudson River erupted, churning with forty-foot waves. Out of the water burst a new chariot-this one pulled by massive hippocampi, who swam in air as easily as in water. My father, glowing with a blue aura of power, rode a defiant circle around the giant's legs. Poseidon was no longer an old man. He looked like himself again-tan and strong with a black beard. As he swung his trident, the river responded, making a funnel cloud around the monster.

"No!" Kronos bellowed after a moment of stunned silence. "NO!"

"NOW, MY BRETHREN!" Poseidon's voice was so loud I wasn't sure if I was hearing it from the smoke image or from all the way across town. "STRIKE FOR OLYM PUS!"

Warriors burst out of the river, riding the waves on huge sharks and dragons and sea horses. It was a legion of Cyclopes, and leading them into battle was . . .

"Tyson!" I yelled.

I knew he couldn't hear me, but I stared at him in amazement. He'd magically grown in size. He had to be thirty feet tall, as big as any of his older cousins, and for the first time he was wearing full battle armor. Riding behind him was Briares, the Hundred-Handed One.

All the Cyclopes held huge lengths of black iron chains-big enough to anchor a battleship-with grap pling hooks at the ends. They swung them like lassos and began to ensnare Typhon, throwing lines around the creature's legs and arms, using the tide to keep circling, slowly tangling him. Typhon shook and roared and yanked at the chains, pulling some of the Cyclopes off their mounts; but there were too many chains. The sheer weight of the Cyclops battalion began to weigh Typhon down. Poseidon threw his trident and impaled the monster in the throat. Golden blood, immortal ichor, spewed from the wound, making a waterfall taller than a skyscraper. The trident flew back to Poseidon's hand.

The other gods struck with renewed force. Ares rode in and stabbed Typhon in the nose. Artemis shot the monster in the eye with a dozen silver arrows. Apollo shot a blazing volley of arrows and set the monster's loincloth on fire. And Zeus kept pounding the giant with lightning, until finally, slowly, the water rose, wrapping Typhon like a cocoon, and he began to sink under the weight of the chains. Typhon bellowed in agony, thrashing with such force that waves sloshed the Jersey shore, soaking five-story buildings and splashing over the George Washington Bridge-but down he went as my dad opened a special tunnel for him at the bottom of the river-an endless waterslide that would take him straight to Tartarus. The giant's head went under in a seething whirlpool, and he was gone.

I mentally cheered in triumph and said, "That's how, Kronos.".

"BAH!" Kronos screamed. He punched through the smoke, tearing the image to shreds.

"They're on their way," I said. "You've lost."

"I haven't even started."

He advanced with blinding speed. Grover-brave, stupid satyr that he was-tried to protect me, but Kronos tossed him aside like a rag doll.

I came forward and engaged him in hand to hand combat. I tried to use what I had been taught at camp (which wasn't much) and punched, kicked and tried every dirty little trick I knew but I couldn't get into his guard. He was too experienced as he been alive for along time and hit me on the chin, knocking me to the ground. His punches hurt like Hades even when I had the Curse of Achilles. I was dazed and tried to get up but I was too tired, he came toward me, probably to beat me to a pulp (as much as he could against me with the Achilles' curse). Then, he stopped, smiled evilly at me and extended his hand and to my horror, the hearth could not stop him and his sword returned.

He leisurely walked towards me and with a two handed grip, held his sword vertically and slashed it downwards. I knew I was invulnerable but still, a sword with a gleaming sharp tip coming down towards me was too much to face and I closed my eyes waiting for the inevitable, but it never came.

"STOP!" Annabeth came from nowhere.

Kronos whirled to face her and slashed at her, but somehow Annabeth caught the strike on her dagger hilt. It was a move only the quickest and most skilled knife fighter could've managed. Don't ask me where she found the strength, but she stepped in closer for leverage, their blades together, and for a moment she stood face-to-face with the Titan lord, holding him at a standstill.

"Luke," she said, gritting her teeth, "I understand now. You have to trust me."

Kronos roared in outrage. "Luke Castellan is dead! His body will burn away as I assume my true form!"

I tried to move, but my body was frozen again. How could Annabeth, battered and half dead with exhaustion, have the strength to fight a Titan like Kronos?

Kronos pushed against her, trying to dislodge his blade, but she held him in check, her arms trembling as he forced his sword down toward her neck.

"Your mother," Annabeth grunted. "She saw your fate."

"Service to Kronos!" the Titan roared. "This is my fate."

"No!" Annabeth insisted. Her eyes were tearing up, but I didn't know if it was from sadness or pain. "That's not the end, Luke. The prophecy: she saw what you would do. It applies to you!"

"I will crush you, child!" Kronos bellowed.

"You won't," Annabeth said. "You promised. You're holding Kronos back even now."

"LIES!" Kronos pushed again, and this time Annabeth lost her balance. With his free hand, Kronos struck her face, and she slid backward.

I summoned all my will. I managed to rise, but it was like holding the weight of the sky again.

Kronos loomed over Annabeth, his sword raised.

Blood trickled from the corner of her mouth. She croaked, "Family, Luke. You promised."

I took a painful step forward. Grover was back on his feet, over by the throne of Hera, but he seemed to be struggling to move as well. Before either of us could get anywhere close to Annabeth, Kronos staggered, dropping his sword.

He stared at the knife in Annabeth's hand, the blood on her face. "Promise."

Then he gasped like he couldn't get air. "Annabeth . . ." But it wasn't the Titan's voice. It was Luke's. He stumbled forward like he couldn't control his own body. "You're bleeding. . . ."

"My knife." Annabeth tried to raise her dagger, but it clattered out of her hand. Her arm was bent at a funny angle. She looked at me, imploring, "Percy, please . . ."

I could move again.

I surged forward and scooped up her knife. Luke hardly paid me any attention. He stepped toward Annabeth, but I put myself between him and her.

"Don't touch her," I said.

Anger rippled across his face. Kronos's voice growled: "Jackson . . ." Was it my imagination, or was his whole body glowing, turning gold?

He gasped again. Luke's voice: "He's changing. Help. He's . . . he's almost ready. He won't need my body anymore. Please-"

"NO!" Kronos bellowed.

"The knife, Percy," Annabeth muttered. Her breath was shallow. "Hero . . . cursed blade . . ."

Luke turned and collapsed, clutching his ruined hands. "Please, Percy . . ."

I struggled to my feet. I moved toward him with the knife. I should kill him. That was the plan.

Luke seemed to know what I was thinking. He moistened his lips. "You can't . . . can't do it yourself. He'll break my control. He'll defend himself. Only my hand. I know where. I can . . . can keep him controlled."

He was definitely glowing now, his skin starting to smoke.

I raised the knife to strike. Then I looked at Annabeth, at Grover cradling her in his arms, trying to shield her. And I finally understood what she'd been trying to tell me.

You are not the hero, Rachel had said. It will affect what you do.

"Please," Luke groaned. "No time."

If Kronos evolved into his true form, there would be no stopping him. He would make Typhon look like a play ground bully.

The line from the great prophecy echoed in my head: A hero's soul, cursed blade shall reap. My whole world tipped upside down, and I gave the knife to Luke.

Grover yelped. "Percy? Are you . . . um . . ."

Yep, that's right I am completely mad, crazy and off my rocker..

But I watched as Luke grasped the hilt.

I stood before him-defenseless.

He unlatched the side straps of his armor, exposing a small bit of his skin just under his left arm, a place that would be very hard to hit. With difficulty, he stabbed himself.

It wasn't a deep cut, but Luke howled. His eyes glowed like lava. The throne room shook, throwing me off my feet. An aura of energy surrounded Luke, growing brighter and brighter. I shut my eyes and felt a force like a nuclear explosion blister my skin and crack my lips.

It was silent for a long time.

When I opened my eyes, I saw Luke sprawled at the hearth. On the floor around him was a blackened circle of ash. Kronos's scythe had liquefied into molten metal and was trickling into the coals of the hearth, which now glowed like a blacksmith's furnace.

Luke's left side was bloody. His eyes were open-blue eyes, the way they used to be. His breath was a deep rattle.

"Good . . . blade," he croaked.

I knelt next to him. Annabeth limped over with Grover's support. They both had tears in their eyes.

Luke gazed at Annabeth. "You knew. I almost killed you, but you knew . . ."

"Shhh." Her voice trembled. "You were a hero at the end, Luke. You'll go to Elysium."

He shook his head weakly. "Think . . . rebirth. Try for three times. Isles of the Blest."

Annabeth sniffled. "You always pushed yourself too hard."

He held up his charred hand. Annabeth touched his fin gertips.

"Did you . . ." Luke coughed and his lips glistened red. "Did you love me?"

Annabeth wiped her tears away. "Yes, Luke, you were my childhood crush and I was and still am in love with you", she said sweetly.

He nodded, but said, "I loved you too, but I can see that you like Percy, though you won't admit it. I am dying, there is no way that we can be together, so go for Percy, he is your second crush after all" he smiled mischievously and winked, "But, can I at least have a good bye kiss". Annabeth didn't answer him, she just leaned down and pressed her lips to his for a long moment.

Once they separated, he smiled brightly (or as much as he could while dying), then winced in pain.

"We can get ambrosia," Grover said. "We can-"

"Grover," Luke gulped. "You're the bravest satyr I ever knew. But no. There's no healing. . . ." Another cough.

He gripped my sleeve, and I could feel the heat of his skin like a fire. "Ethan. Me. All the unclaimed. Don't let it . . . Don't let it happen again."

His eyes were angry, but pleading too.

"I won't," I said. "I promise."

Luke nodded, and his hand went slack.

The gods arrived a few minutes later in their full war regalia, thundering into the throne room and expecting a battle with Kronos, King of Titans.

What they found were Annabeth, Grover, and me standing over the body of a broken half-blood, in the dim warm light of the hearth.

"Percy," my father called, awe in his voice. "What . . . what is this?"

I turned and faced the Olympians.

"We need a shroud," I announced, my voice cracking. "A shroud for the son of Hermes."
