The Last Olympian

gushed from the rocks and roared off in a cascade of rapids. To our left, far away in the gloom, fires burned on the ramparts of Erebus, the great black walls of Hades’s kingdom.
    I shuddered. I’d first been here when I was twelve, and only Annabeth and Grover’s company had given me the courage to keep going. Nico wasn’t going to be quite as helpful with the “courage” thing. He looked pale and worried himself.
    Only Mrs. O’Leary acted happy. She ran along the beach, picked up a random human leg bone, and romped back toward me. She dropped the bone at my feet and waited for me to throw it.
    “Um, maybe later, girl.” I stared at the dark waters, trying to get up my nerve. “So, Nico . . . how do we do this?”
    “We have to go inside the gates first,” he said.
    “But the river’s right here.”
    “I have to get something,” he said. “It’s the only way.”
    He marched off without waiting.
    I frowned. Nico hadn’t mentioned anything about going inside the gates. But now that we were here, I didn’t know what else to do. Reluctantly, I followed him down the beach toward the big black gates.
    Lines of the dead stood outside waiting to get in. It must’ve been a heavy day for funerals, because even the EZ-DEATH line was backed up.
    “Woof!” Mrs. O’Leary said. Before I could stop her she bounded toward the security checkpoint. Cerberus, the guard dog of Hades, appeared out of the gloom—a three-headed rottweiler so big he made Mrs. O’Leary look like a toy poodle. Cerberus was half transparent, so he’s really hard to see until he’s close enough to kill you, but he acted like he didn’t care about us. He was too busy saying hello to Mrs. O’Leary.
    “Mrs. O’Leary, no!” I shouted at her. “Don’t sniff . . . Oh, man.”
    Nico smiled. Then he looked at me and his expression turned all serious again, like he’d remembered something unpleasant. “Come on. They won’t give us any trouble in the line. You’re with me.”
    I didn’t like it, but we slipped through the security ghouls and into the Fields of Asphodel. I had to whistle for Mrs. O’Leary three times before she left Cerberus alone and ran after us.
    We hiked over black fields of grass dotted with black poplar trees. If I really died in a few days like the prophecy said, I might end up here forever, but I tried not to think about that.
    Nico trudged ahead, bringing us closer and closer to the palace of Hades.
    “Hey,” I said, “we’re inside the gates already. Where are we—”
    Mrs. O’Leary growled. A shadow appeared overhead— something dark, cold, and stinking of death. It swooped down and landed in the top of a poplar tree.
    Unfortunately, I recognized her. She had a shriveled face, a horrible blue knit hat, and a crumpled velvet dress. Leathery bat wings sprang from her back. Her feet had sharp talons, and in her brass-clawed hands she held a flaming whip and a paisley handbag.
    “Mrs. Dodds,” I said.
    She bared her fangs. “Welcome back, honey.”
    Her two sisters—the other Furies—swooped down and settled next to her in the branches of the poplar.
    “You know Alecto?” Nico asked me.
    “If you mean the hag in the middle, yeah,” I said. “She was my math teacher.”
    Nico nodded, like this didn’t surprise him. He looked up at the Furies and took a deep breath. “I’ve done what my father asked. Take us to the palace.”
    I tensed. “Wait a second, Nico. What do you—”
    “I’m afraid this is my new lead, Percy. My father promised me information about my family, but he wants to see you before we try the river. I’m sorry.”
    “You tricked me?” I was so mad I couldn’t think. I lunged at him, but the Furies were fast. Two of them swooped down and plucked me up by the arms. My sword fell out of my hand, and before I knew it, I was dangling sixty feet in the air.
    “Oh, don’t struggle, honey,” my old math teacher cackled in my ear. “I’d hate to drop you.”
    Mrs. O’Leary barked angrily and jumped, trying to reach me, but we were too high.
    “Tell Mrs. O’Leary to behave,” Nico warned. He was hovering near me in the clutches of the third Fury. “I don’t want her to get hurt, Percy. My father is waiting. He just wants to talk.”
    I wanted to tell Mrs. O’Leary to attack Nico, but it wouldn’t have done any good, and Nico was right about one thing: my dog could get hurt if she tried to pick a fight with the Furies.
    I gritted my teeth. “Mrs. O’Leary,
