Caldera gave a roar that was half rage and half pain, and struck at Ja-Ja with the ferocity of a wounded bear. I heard the crack as her blow landed and Ja-Ja went flying down the corridor, but Caldera stumbled and went to one knee. She was up again in an instant and I knew combat reflexes were keeping her moving—you never stay down in a fight, you always get up as fast as you can—but she was swaying and I could tell she was badly hurt.

Ja-Ja picked himself up. Caldera’s punch should have broken his bones but my heart sank as I looked at him and I saw that he was smiling. Whatever he’d taken from Caldera, it had been enough to let him shrug off the hit. “Tastes nice,” he said. “I could go for dessert.”

“What the fuck are you doing?” Captain America snapped at Ja-Ja. He was still holding his gun, but he wasn’t aiming it at me anymore.

“We said don’t hurt her!” Dhruv shouted.

Ja-Ja gave Dhruv a contemptuous look. “Yeah, you were doing so great.”

Will was hesitating, looking between Caldera and Ja-Ja. For the moment the adepts were distracted but I knew it wouldn’t last. One of the metal spheres Dhruv had been firing at me was lying on the floor, and I scooped it up. “Caldera!” I said sharply with a note of command in my voice. “Watch!”

Caldera turned, hurt but angry, and Sonder did as well. Before Caldera could speak, I flicked the sphere back down the corridor. It glanced off the wall and through the archway down to the basement, and I heard the clack-clack-clack as it went bouncing down the steps. Caldera and Sonder stared for a second, then their eyes went wide at the same instant. I put my finger to my lips.

“Keeper,” Will said, and all three of us turned to look at him. He was frowning at Caldera. “We’re not here for you. You and the time mage can go. We just want Verus.”

Caldera looked back at him, then gave him the finger.

Captain America raised his eyebrows; he actually looked impressed. Ja-Ja looked eager, and I knew he was hoping Caldera would say no. Will just looked pissed off. “You aren’t going to win this,” he said. “Get out of—”

The nocturne came out of the shadows, homing in on Will like iron filings to a magnet. Its body was black smoke and blended into the darkness behind it so perfectly that only its blue-white eyes were visible. Will leapt back, eyes going wide in shock, but even he wasn’t quick enough and a tendril of darkness twined around his leg, yanking him off his feet.
