Free Thin Air by Rachel Caine

were chattering by the time I arrived, and Lewis paused in the act of shouldering his pack to toss me a chemical heat pack.
    â€œOpen it, rub the pack, and put it in your shirt,” he said. “It’ll help keep your core temp up.”
    I tore the package open and shook out what looked like a really big sachet, rubbed it between my palms, and was instantly rewarded with a burst of steady heat. I dropped it down my buttoned-up shirt, between shirt and undershirt, and gave Lewis a trembling good-to-go high sign. My fingernails were a little blue. I scrambled into my coat and gloves, and hefted my own backpack. It clunked with plastic water bottles.
    â€œEnjoy your bath?” Lewis asked. His tone was about as neutral as you could get, so I couldn’t read anything into it. I just nodded. “Good. Let’s move out.”
    â€œWhat about Kevin and Cherise? Do you think they’re still…?”
    â€œDavid’s scouting,” he said. “He’ll warn us if they come anywhere close.”
    He took off. I had no choice but to follow.

    I’ll skip over the day from hell, which was spent scrambling through razor-edged brush, climbing steep hills of loose shale, falling, cursing, sweating, panting, and generally having the sort of outdoor experience most city girls dread. I had no affinity for this whole hiking thing, and while the outdoors looked pretty, as far as I was concerned it’d look even prettier seen from the window of a passing car.
    When my road-show Daniel Boone finally called a permanent halt, it was because of the snow. Flakes had begun to drift silently out of the clouds just an hour after we’d started the trek, light and whispery and dry, brushing against my sweaty face like cool feathers. At first I’d been grateful for it, but that was before it started to stick to the cold ground. A few random flurries became a full-fledged blizzard within the next couple of hours, and what started out a nuisance became more of a hardship with every trudging step. Lewis held my hand, and sometimes the only thing real in the world seemed to be the pressure of his hold on me. I sometimes heard rumbles, as if miles up it was raining, and I supposed I ought to feel grateful that it wasn’t sleeting. Sleet would have been a step down, circles-of-hell-wise.
    No cave this time, but Lewis put up the tent and we crawled inside, into our sleeping bags, too tired to do more than murmur a couple of words before sleep sucked us down. I wanted to ask Lewis where we were going, but I didn’t have the energy. I no longer cared all that much, frankly. Just kill me and get it over with , I thought. I ached all over, and I was still aching when, with the suddenness of a light switched off, I fell asleep.
    It didn’t even occur to me to wonder where David was, or why he hadn’t joined us. The ways of the Djinn, I’d already guessed, were not necessarily easy to figure out, even if you were dating one.
    I woke up alone. All alone. The tent was silent, not even a breeze rattling the fabric, and it was deeply dark. And very, very cold. The chemical pack I’d gone to sleep with was an inert, stiff, dead thing next to me in the bag, and my hands had taken on a waxy chill. I burrowed deeper in the sleeping bag, conserving warmth, and listened for some sign that Lewis was up and around and doing something useful, like making the weather balmy or at least making coffee.
    It was quiet as a grave out there.
    â€œLewis?” I whispered it, because somehow it seemed like the time and place to whisper. No response. I contemplated staying where I was, but that didn’t seem practical in the long term. Lewis’s sleeping bag was neatly rolled up and attached to his pack, which was leaning where his body had been when I’d fallen asleep. I crept out, wrapped myself quickly in my coat, jammed gloves on my hands and a knit cap over my head, and ducked out of the tent
