The air suddenly felt a lot heavier in my lungs. Despite the large number of impossible things that had happened to me lately, my brain couldn't quite seem to deal. It was loudly insisting that huge slabs of rock that weighed maybe a ton each didn't just hover in the air and that we were both going to die any second now.

I made a small, choked sound, but managed to swallow the bubble of hysteria before it could tear loose. If Pritkin had been a second later getting his protection back up, there would be four new bodies entombed down here instead of two. But there weren't. We were safe. Sort of.

Pritkin had rolled onto his back and was staring at me, hard and intent. "This is exactly why I told you to go home."

"I have a devastating comeback for that," I informed him with dignity. "Just not right now."

"Do you want to give up?" I blinked. I could count on zero fingers the number of times he had asked my opinion. "Because there are almost certainly more of them back there."

I remembered the ghost saying that there were twelve mages all together. Which meant that behind the rockfall, ten more were still hanging around, unless they were caught somewhere I couldn't see. Or unless they'd left, assuming that the cave-in had killed us. But no, I wasn't that lucky.

"You know what's at stake," I reminded him.

"I thought you'd say that." Pritkin levered himself to his knees with a grunt. The rubble shifted along with him, enough to bring another large slab crashing down. The jagged underside landed only a few feet away from my face.

Pritkin's voice, laced with its usual impatience, cut through my panic. "Let's go."

"Go?" It came out as more of a squeak than I'd intended. "How? Because I can shift us back home but I can't shift us beyond this. I don't know what's on the other side or even where the other side is—"

"Just stay close." Before he'd even finished speaking, his shields had changed from fluid waves to hard crystal, reflecting the cave-in through a hundred sharp facets. A few more rocks fell off, allowing more to rain down from above, striking off the new, rigid surface with dull thuds. Pritkin started crawling forward, and his shields went with him, almost scooping me off my feet before I got with the program and moved up close behind him.

It wasn't until I saw the body of one of the mages slide down the side and roll behind us that I completely realized what was happening. Our small bubble was plowing through the rocks and dirt like a crystal mole intent on making a new burrow. We hit a wall once, looking for an entrance that wasn't there, but we found it a few feet to the left and burst through, the cave collapsing in on itself behind us.

Pritkin dropped his shields with an audible sigh, and the dust we'd dislodged in our escape flooded in, almost blinding me. We forged ahead to get away from the choking cloud, which had no way to disperse in an area without wind or open air. But before we'd gone ten yards, we ran into what felt like another cave-in.

Once I blinked the dirt out of my eyes, I realized what I was seeing. A narrow tunnel stretched out in front of us, filled halfway to the ceiling with what looked like a mile of bones. Pritkin climbed on top of the broken human mass, flashing the light around. "There's a hole in the wall up ahead. It probably leads to another tunnel."

I eyed the pile of bones uneasily. Anything kept in close proximity to a person's aura eventually imprints with a psychic skin. I'd experienced more horror stories from inadvertently brushing up against a strong trigger than I could count. And I couldn't think of a stronger trigger than an actual body part.

"Hurry, damn it!" Pritkin thrust a hand down to me as the sound of voices echoed dimly from the corridor behind us. Somebody had heard our exit.

I hefted myself up gingerly, before I could think about it too much. The bones were old and dry, and crunched sickeningly under my weight. Many splintered, sending little knives into my palms and tearing my jeans, but there were no psychic flashes. Moving them must have ruptured any imprints that had formed.

When Pritkin said a hole in the wall, he wasn't kidding. I could barely squeeze through the thing, and it sounded from his language like he'd scraped off more than a little skin himself. "Move!" he whispered, giving me a push in the small of my back. I scrambled inside the small rock-hewn cavern on the other side of the hole, and almost tumbled down a set of stairs that started after only a few feet.

The claustrophobically low stairwell was extremely uninviting; mostly I just saw the darkness that pooled in every niche and corner. I really didn't want to go down there. Then a spell hit the ceiling behind me with a crack like cannon fire and I reconsidered, scrambling down the stairs ahead of Pritkin.

A second spell hit while we were still on the steps. It went on and on, like a slow-motion bomb blast, causing gravel to pepper the back of my hands and neck like hail. It sent me sliding down the stairs, but the vibrations rode up through my legs, making it almost impossible to find a foothold. And then it didn't matter because there was no foothold to find. The rock disintegrated beneath my feet, and I tumbled through darkness and empty air before slamming into freezing water.

It took me a moment to realize I wasn't drowning. The water came only up to my waist, but it was like ice and the cold shot right up my spine. Worse was the by-now-familiar billowing cloud of dust, trapping me in a choking haze. Instinctively, I sloshed farther away from the rockfall, trying to breathe, and found myself treading water. I grabbed a moss-covered skull that jutted out from the wall, my fingers finding purchase in the eye sockets. I held on, too grateful to be repulsed, gasping in great lungfuls of air.

"Pritkin!" It was barely a croak, but a moment later the flashlight beam hit my eyes, blinding me.

"Still alive?"

I tried to answer, but my lungs decided this would be a good moment to expel all the foreign matter I'd breathed in, and I ended up heaving and choking. I lost my grip on the slimy bone and slid under the frigid water. For a long, terrifying moment, I was lost in an endless sea of black that immediately chilled me to the core. Then two broad hands were fumbling for a grip on my shoulders, pulling me back to the surface, reminding me where up and down were.

"Miss Palmer!"

I spat out a mouthful of limestone paste, the result of oily water mixed with dust, and gasped in some air. "Damn right."

Pritkin nodded and flashed the light around, giving glimpses of a corridor where the floor rippled oddly and everything was suddenly shades of gray and pale, unearthly green. It looked like the entire lower levels had flooded. I can swim, but I wasn't in love with the idea of navigating a dark underground stream with barely enough headroom to breathe.

"I'll deal with this," Pritkin said grimly. "Shift out of here."

"And if they keep coming?"

"I'll manage."

And he called me bloody-minded. I took another breath to inform my lungs that asphyxiation would have to wait, and pushed back off into the flood. "Just swim."

Pritkin didn't answer, unless you count a curse, although that could have been due to the spell that hit the water behind us, instantly raising the temperature from chilled to boiling. I screamed, and coherent thought fled. I didn't think, just grabbed his hand and shifted.

A second later, we landed in the same corridor, but with no dust cloud, no mages and no flood. I'd been treading water in the other time, so I was only a few feet off the ground. Pritkin, unfortunately, had been floating, and he fell from a little farther. Like about six feet.

He hit the rocky floor with a thud, a curse and a crack, the last from the demise of the flashlight. I tried to ask how he was, but a stitch was biting deep into my side and, for a long moment it was impossible to draw oxygen into my lungs. I slid down the wall to a seated position because my knees suddenly felt too rubbery to be reliable.
