I leaned over the edge of the hole. Lying tight against the wall was Annah, stripped to her underwear and blood drenching her left arm, but still very much alive.

She looked at me and smiled. "Keepers might be good with electrical things, but they sure are lousy shots."

I held her in my arms as Impervia bandaged Annah's only wound: a bullet had passed in and out of her left biceps muscle, missing the bone and all major blood vessels. As she'd said, the Keeper had been a lousy shot-not too surprising for a man who'd lost one eye and was dazed from being battered unconscious. All but one of the bullets had gone wild, and the hypersonic stun-wave was off target too.

Annah would still have been cremated by the flamethrower if not for quick work by the Caryatid-our mistress of fire had redirected the blaze back at the shooter before Annah was hit. (Good-bye, poor misguided Keeper.) That left only the acid, also badly aimed; Annah's thick winter outfit protected her from the caustic splash, and she'd managed to peel off her clothes before the corrosive fluids ate through to her flesh. (Smoke still rose from the discarded bundle of cloth. Her long parka was pocked through with holes, as if chewed by huge moths. The black cloak that let her vanish in the dark had vanished itself-totally consumed by the ravaging chemicals.)

But Annah was safe. Shot, yes, and trying not to wince as Impervia wrapped bright white bandages around her dark arm; but when I considered the alternative…

I held her tightly and lowered my face against the top of her head. I didn't cry; I just breathed in the warm fragrance of her hair.

"Phil… Phil!" The Caryatid was shaking my shoulder. "We have to get going right now."

"Can't we let Annah rest-"

"No," the Caryatid interrupted. "I heard voices up the elevator shaft. They're whispering, but the shaft carries echoes a long way."

"Probably the Ring of Knives," Impervia said. "No doubt, Mother Tzekich has been running around Niagara Falls, asking at every hotel if they've seen Sebastian and her daughter. She must have found someone who saw the two heading this way."

Either that, I thought, or Tzekich noticed the Falls had stopped flowing and came to investigate. She'd have seen Pelinor's body in the roadway, immediately in front of the power plant. After that, it was just a matter of following our tracks.

Annah put her hand on my cheek. She was bandaged now-looking painfully vulnerable in nothing but underwear, and probably weak from blood loss-but her smile was genuine. "We have to go before they get here. I'm strong enough. Really."

I helped her to her feet. As I did, Impervia slipped off her own winter coat and draped it around Annah's shoulders. "No," I said, "I'll give her my coat."

"She's already got mine," Impervia said. "I don't need it-this place is heated. Anyway, a coat will only slow me down if the time comes for… punishing the wicked."

Impervia smacked her right fist into her left palm. I stifled a laugh. In the past twenty-four hours, Impervia had been kicked by fishermen, gut-punched by Hump, kicked by Zunctweed, tossed around by Sebastian… and still she was looking for a fight.

Annah whispered softly in my ear, "That's what happens to some people when they take a vow of celibacy."

When I stifled the laugh this time, I nearly hurt myself.

I kept my arm around Annah as we moved forward; I don't know if she really needed my support, but she didn't push me away.

As we passed the fallen Keepers, Annah suddenly stopped. I thought she just needed to rest-but she bent down and pried an Element gun from its dead owner's grip.

"You want one too?" she asked.

Thinking of Pelinor and Myoko, I nodded. This was not just a quest; this was war.

A single door led forward. It had once been equipped with a fancy electronic lock connected to a keypad. Half the keypad was missing now, along with a chunk of the door frame. Sebastian hadn't wasted time on delicacy.

Beyond lay a short corridor with a door in each side wall and another at the far end. All three doors had been blown off their hinges.

The side doorways opened into locker rooms where the plant's OldTech personnel had changed from street clothes into whatever work-suits they wore on the job. The lockers had been knocked helter-skelter, some tossed against the walls, others cracked open like eggs. I wondered if Sebastian had smashed around the lockers just to show he could… or because he'd begun to like pointless mayhem.

Our friend Caryatid had also developed a liking for displays of mystical force. Before this business started, I'd never seen her juggle flames any larger than a big candle-but now she'd built a blaze the size of a cow's head, floating in front of us at chest height and pouring out heat like a furnace. No one dared step within five paces of it… no one except the Caryatid, whose face glistened with heat-sweat. She barely seemed to notice; she and her flameball just plowed ahead toward the next smashed-in doorway.

The entrance to the main machine room.

The place was as big as the academy's main building: a single chamber more than four stories high and a hundred meters square, its ceiling supported by dozens of pillars. The walls and floors were painted kelp-green; they tinted the space like a sea-grotto, ripe and weedy. In OldTech times, the place must have been brightly lit-bank upon bank of fluorescent fixtures hung from the roof, with multiple light-tubes in each fixture. But the days were long gone when such tubes could be mass-produced. Three-quarters of the fixtures had no light at all, and the remainder each only held a single long bulb. The result was an oceanic dimness, a full-fathom-five gloom filled with shadows.

Most of the shadows came from huge turbines held down by massive bolts that passed through the plastic floor and down into firmer footings below… possibly all the way to bedrock. The turbines were great hulking things with monstrous cooling fans, the actual turbine blades unseen under thick metal hoods. Water from the Falls ran through pipes beneath the false floor, rushing through the turbines and out again to the river. I had the impression this place should be deafeningly loud-roaring water, spinning metal, whirling fans-but the room had gone lethally silent. With the Falls dammed up, the tumult was suspended.

We could see no movement. No one was close to the door we'd just entered, and our view farther in was blocked by the ponderous machinery. A single corpse lay halfway between us and the nearest turbine: a middle-aged woman in brown Keeper's habit, facedown with a spill of moist white nuggets puddled on the floor beneath her. After choking her, the white goo had dribbled out of her mouth. The Caryatid dispatched a fireball to incinerate the alien curds; they burned with a hissing splutter, the only sound in the whole cavernous space.

Impervia turned to the rest of us and mouthed, Wait; listen. Annah and I obeyed. The Caryatid didn't. She gave her flames a moment to finish charring the last of the curds (filling the air with the smell of meat as the Keeper's face roasted), then she and her fireball moved forward. We hurried after her, fanning out so we weren't easy fodder for a single burst from an Element gun. Even Annah moved off on her own, wearing Impervia's too-big coat and cradling the Element gun in her arms. When I tried to tag along behind her, she waved me off: all her concentration was focused on the room before us, eyes and ears straining for any sign of trouble.

So we moved forward-like a platoon in enemy territory, walking silently in a line between trees. In our case, the "trees" were giant steel generators, two stories tall, their cooling fans motionless. The sparse lighting proved the station still had power, but it must have been coming from batteries; the turbines had all run dry.
