I slung it off my shoulder and unzipped it . Inside was a two-foot-long metal cylinder, spiked on both ends, humming with energy.
"Percy," Annabeth said. "How—"
"I—I don't know. I don't understand."
"You heroes are always the same," Hades said. "Your pride makes you foolish, thinking you could bring such a weapon before me. I did not ask for Zeus's master bolt, but since it is here, you will yield it to me. I am sure it will make an excellent bargaining tool. And now ... my helm. Where is it?"
I was speechless. I had no helm. I had no idea how the master bolt had gotten into my backpack. I wanted to think Hades was pulling some kind of trick. Hades was the bad guy. But suddenly the world turned sideways. I realized I'd been played with. Zeus, Poseidon, and Hades had been set at each other's throats by someone else. The master bolt had been in the backpack, and I'd gotten the backpack from ...
"Lord Hades, wait," I said. "This is all a mistake."
"A mistake?" Hades roared.
The skeletons aimed their weapons. From high above, there was a fluttering of leathery wings, and the three Furies swooped down to perch on the back of their master's throne. The one with Mrs. Dodds's face grinned at me eagerly and flicked her whip.
"There is no mistake," Hades said. "I know why you have come—I know the real reason you brought the bolt. You came to bargain for her."
Hades loosed a ball of gold fire from his palm. It exploded on the steps in front of me, and there was my mother, frozen in a shower of gold, just as she was at the moment when the Minotaur began to squeeze her to death.
I couldn't speak. I reached out to touch her, but the light was as hot as a bonfire.
"Yes," Hades said with satisfaction. "I took her. I knew, Percy Jackson, that you would come to bargain with me eventually. Return my helm, and perhaps I will let her go. She is not dead, you know. Not yet. But if you displease me, that will change."
I thought about the pearls in my pocket. Maybe they could get me out of this. If I could just get my mom free ...
"Ah, the pearls," Hades said, and my blood froze. "Yes, my brother and his little tricks. Bring them forth, Percy Jackson."
My hand moved against my will and brought out the pearls.
"Only three," Hades said. "What a shame. You do realize each only protects a single person. Try to take your mother, then, little godling. And which of your friends will you leave behind to spend eternity with me? Go on. Choose. Or give me the backpack and accept my terms." I looked at Annabeth and Grover. Their faces were grim.
"We were tricked," I told them. "Set up."
"Yes, but why?" Annabeth asked. "And the voice in the pit—"
"I don't know yet," I said. "But I intend to ask."
"Decide, boy!" Hades yelled.
"Percy." Grover put his hand on my shoulder. "You can't give him the bolt,"
"I know that."
"Leave me here," he said. "Use the third pearl on your mom."
"No!"
"I'm a satyr," Grover said. "We don't have souls like humans do. He can torture me until I die, but he won't get me forever. I'll just be reincarnated as a flower or something. It's the best way."
"No." Annabeth drew her bronze knife. "You two go on. Grover, you have to protect Percy. You have to get your searcher's license and start your quest for Pan. Get his mom out of here. I'll cover you. I plan to go down fighting."
"No way," Grover said. "I'm staying behind."
"Think again, goat boy," Annabeth said.
"Stop it, both of you!" I felt like my heart was being ripped in two. They had both been with me through so much. I remembered Grover dive-bombing Medusa in the statue garden, and Annabeth saving us from Cerberus; we'd survived Hephaestus's Waterland ride, the St. Louis Arch, the Lotus Casino. I had spent thousands of miles worried that I'd be betrayed by a friend, but these friends would never do that. They had done nothing but save me, over and over, and now they wanted to sacrifice their lives for my mom.
"I know what to do," I said. "Take these."
I handed them each a pearl.
Annabeth said, "But, Percy ..."
I turned and faced my mother. I desperately wanted to sacrifice myself and use the last pearl on her, but I knew what she would say. She would never allow it. I had to get the bolt back to Olympus and tell Zeus the truth. I had to stop the war. She would never forgive me if I saved her instead. I thought about the prophecy made at HalfBlood Hill, what seemed like a million years ago. You will fail to save what matters most in the end.
"I'm sorry," I told her. "I'll be back. I'll find a way." The smug look on Hades's face faded. He said, "Godling ... ?"
"I'll find your helm, Uncle," I told him. "I'll return it. Remember about Charon's pay raise."
"Do not defy me—"
"And it wouldn't hurt to play with Cerberus once in a while. He likes red rubber balls."
"Percy Jackson, you will not—"
I shouted, "Now, guys!"
We smashed the pearls at our feet. For a scary moment, nothing happened. Hades yelled, "Destroy them!"
