“Blood trickled from the corner of her (Annabeth) mouth. She croaked, "Family, Luke. You promised."Luke 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. . . ." He gasped again."He's changing. Help. He's . . . he's almost ready. He won't need my body anymore. Please—""The knife, Percy," Annabeth muttered. Her breath was shallow. "Hero . . . cursed blade . . ."Luke turned and collapsed, clutching his ruined hands."Please, Percy . . ."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."I raised the knife to strike. Then I looked at Annabeth, at Grover. 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. 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.I watched as Luke grasped the hilt he stabbed himself”

“Something was wrong with Luke," Annabeth muttered, poking at the fire with her knife. "Did you notice the way he was acting?""He looked pretty pleased to me," I said. "Like he'd spent a nice day torturing heroes.""That's not true! There was something wrong with him. He looked...nervous. He told his monsters to spare me. He wanted to tell me something.""Probably, 'Hi, Annabeth! Sit here with me and watch while I tear your friends apart. It'll be fun!”

“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.”

“A little background: Annabeth used to adventure with Hermes's son Luke. Over time, Annabeth developed a crush on Luke. As Annabeth got older, Luke developed feelings for her, too. Luke turned evil. Hermes blamed Annabeth for not preventing Luke from turning evil. Annabeth blamed Hermes for being a rotten dad and giving Luke the capacity to become evil in the first place. Luke died in war. Hermes and Annabeth blamed each other.Confused? Welcome to my world.”

“When Luke had descended into the River Styx, he would've had to focus on something important that would hold him to his mortal life. Otherwise he would've dissolved. I had seen Annabeth, and I had a feeling he had too. He had pictured that scene Hestia showed me—of himself in the good old days with Thalia and Annabeth, when he promised they would be a family. Hurting Annabeth in battle had shocked him into remembering that promise. It had allowed his mortal conscience to take over again, and defeat Kronos. His weak spot—his Achilles heel—had saved us all”

“I couldn't help thinking about my dream, with Annabeth crumpled and lifeless in Luke's arms. Here I was rescuing baby monsters, but I couldn't save my friend.”

“Annabeth hesitated. "Then we'll all go." "No," I said. "It's too dangerous. If they got hold of Nico, or Rachel for that matter, Kronos could use them.You stay here and guard them."What I didn't say: I was also worried about Annabeth. I didn't trust what she would do if she saw Luke again. He had fooled her and manipulated her too many times before."Percy, don't," Rachel said. "Don't go up there alone.""I'll be quick," I promised. "I won't do anything stupid."Annabeth took her Yankees cap out of her pocket. "At least take this. And be carful.""Thanks." I remembered the last time Annabeth and I had parted ways, when she'd given me a kiss for luck in Mount St. Helens. This time, all I got was the hat.”
