It was a smart idea, but I guess it's not so easy when your shoes are pulling you along feetfirst at full speed. Grover tried to sit up, but he couldn't get close to the laces. We kept after him, trying to keep him in sight as he ripped between the legs of spirits who chattered at him in annoyance.
I was sure Grover was going to barrel straight through the gates of Hades's palace, but his shoes veered sharply to the right and dragged him in the opposite direction. The slope got steeper. Grover picked up speed. Annabeth and I had to sprint to keep up. The cavern walls narrowed on either side, and I realized we'd entered some kind of side tunnel. No black grass or trees now, just rock underfoot, and the dim light of the stalactites above.
"Grover!" I yelled, my voice echoing. "Hold on to something!"
"What?" he yelled back.
He was grabbing at gravel, but there was nothing big enough to slow him down. The tunnel got darker and colder. The hairs on my arms bristled. It smelled evil down here. It made me think of things I shouldn't even know about—blood spilled on an ancient stone altar, the foul breath of a murderer.
Then I saw what was ahead of us, and I stopped dead in my tracks.
The tunnel widened into a huge dark cavern, and in the middle was a chasm the size of a city block.
Grover was sliding straight toward the edge.
"Come on, Percy!" Annabeth yelled, tugging at my wrist.
"But that's—"
"I know!" she shouted. "The place you described in your dream! But Grover's going to fall if we don't catch him." She was right, of course. Grover's predicament got me moving again. He was yelling, clawing at the ground, but the winged shoes kept dragging him toward the pit, and it didn't look like we could possibly get to him in time.
What saved him were his hooves.
The flying sneakers had always been a loose fit on him, and finally Grover hit a big rock and the left shoe came flying off. It sped into the darkness, down into the chasm. The right shoe kept tugging him along, but not as fast. Grover was able to slow himself down by grabbing on to the big rock and using it like an anchor.
He was ten feet from the edge of the pit when we caught him and hauled him back up the slope. The other winged shoe tugged itself off, circled around us angrily and kicked our heads in protest before flying off into the chasm to join its twin.
We all collapsed, exhausted, on the obsidian gravel. My limbs felt like lead. Even my backpack seemed heavier, as if somebody had filled it with rocks.
Grover was scratched up pretty bad. His hands were bleeding. His eyes had gone slit-pupiled, goat style, the way they did whenever he was terrified.
"I don't know how ..." he panted. "I didn't..."
"Wait," I said. "Listen."
I heard something—a deep whisper in the darkness.
Another few seconds, and Annabeth said, "Percy, this place—"
"Shh." I stood.
The sound was getting louder, a muttering, evil voice from far, far below us. Coming from the pit.
Grover sat up. "Wh—what's that noise?"
Annabeth heard it too, now. I could see it in her eyes. "Tartarus. The entrance to Tartarus." I uncapped Anaklusmos.
The bronze sword expanded, gleaming in the darkness, and the evil voice seemed to falter, just for a moment, before resuming its chant.
I could almost make out words now, ancient, ancient words, older even than Greek. As if ...
"Magic," I said.
"We have to get out of here," Annabeth said.
Together, we dragged Grover to his hooves and started back up the tunnel. My legs wouldn't move fast enough. My backpack weighed me down. The voice got louder and angrier behind us, and we broke into a run.
Not a moment too soon.
A cold blast of wind pulled at our backs, as if the entire pit were inhaling. For a terrifying moment, I lost ground, my feet slipping in the gravel. If we'd been any closer to the edge, we would've been sucked in.
We kept struggling forward, and finally reached the top of the tunnel, where the cavern widened out into the Fields of Asphodel. The wind died. A wail of outrage echoed from deep in the tunnel. Something was not happy we'd gotten away.
"What was that?" Grover panted, when we'd collapsed in the relative safety of a black poplar grove. "One of Hades's pets?"
Annabeth and I looked at each other. I could tell she was nursing an idea, probably the same one she'd gotten during the taxi ride to L.A., but she was too scared to share it. That was enough to terrify me.
I capped my sword, put the pen back in my pocket. "Let's keep going." I looked at Grover.
"Can you walk?"
He swallowed. "Yeah, sure. I never liked those shoes, anyway." He tried to sound brave about it, but he was trembling as badly as Annabeth and I were. Whatever was in that pit was nobody's pet. It was unspeakably old and powerful. Even Echidna hadn't given me that feeling. I was almost relieved to turn my back on that tunnel and head toward the palace of Hades.
Almost.
