Chill looks like he’s ready to hurl an icicle into her eye. “What the hell is she doing here?”

“Helping me.”

“A little less chatting and a little more lockpicking, please?” she growls.

“I’m trying, but these locks are older than . . .” Lyon’s name jams in my throat, and I push that thought away. “The locks are old. It may take me a while.” I fight back a shiver. “Lighten up, Chill. This is going to take a lot longer if my hands are cold.”

He glares at Kai over my head. “No one’s coming. The Guards tore out of here a while ago. They’re all out looking for Fleur. She can’t have gone far. As soon as you get this cell open, we can go find her and the others and get the hell out of—”

The ground heaves under me, throwing me backward and tossing my picks. Chill’s grip on the bars is the only thing holding him upright as the cavern shakes. Dust billows through the corridor as the walls splinter around us. Kai wobbles left, then right, staggering into a cell door and holding herself up against the bars. I rush to recover my spilled picks, bracing myself against another wave of tremors.

“That doesn’t bode well,” Chill says when the ground finally stills. “They must have found her. Doug’s probably taking her back.”

“Back here?” My heart leaps as I realize how close she is. How soon I might see her.

Chill’s eyes meet mine, apologies swirling inside them.

“Back where? Where’s he keeping her, Chill?”

“In his suite in the north wing.”

His suite. Michael’s apartment.

I plunge a pick back into the lock, surprised frost isn’t crackling over my fingers. “When I open this door, you’re going to take Kai to the Winter wing and find a computer. Hack the Control Room servers and find the number of Névé Onding’s room—”

“Névé Onding?” Chill asks. “But Névé Onding is—”

“Kai’s sister.” I glance up sharply from the lock. His mouth falls open and his eyebrows rise. “Kai helped me get down here on the condition that we help her find her sister,” I explain. “After you find Névé’s room number, you’ll split up. She’ll go looking for her sister while you go to the Autumn wing to find Poppy and the others. I’ll meet you by the incinerator under the Winter wing in three hours. That should give us both plenty of time.” I pop the lock and press Lyon’s map and my flashlight into Chill’s hands.

“Where are you going?” he asks.

“I’m going to find Fleur.”

Kai doesn’t argue. If anything, she seems as eager as I am to get out of here and start hunting. I turn and start running down the hall, back toward the Winter wing.
