I got to know a little about the humans around me, mostly just by listening to them. I learned their names, at least. The caramel-skinned woman was named Lily, and she was from Philadelphia. She had a dry sense of humor and got along well with everyone because she never got ruffled. The young man with the bristly black hair, Wes, stared at her a lot, but she never seemed to notice that. He was only nineteen, and he’d escaped from Eureka, Montana. The sleepy-eyed mother was named Lucina, and her two boys were Isaiah and Freedom—Freedom had been born right here in the caves, delivered by Doc. I didn’t see much of these three; it seemed that the mother kept her children as separate from me as was possible in this limited space. The balding, red-cheeked man was Trudy’s husband; his name was Geoffrey. They were often with another older man, Heath, who had been Geoffrey’s best friend since early childhood; the three had escaped the invasion together. The pallid man with the white hair was Walter. He was sick, but Doc didn’t know what was wrong with him—there was no way to find out, not without labs and tests, and even if Doc could diagnose the problem, he had no medicine to treat it. As the symptoms progressed, Doc was starting to think it was a form of cancer. This pained me—to watch someone actually dying from something so easily fixed. Walter tired easily but was always cheerful. The white-blond woman—her eyes contrastingly dark—who’d brought water to the others that first day in the field was Heidi. Travis, John, Stanley, Reid, Carol, Violetta, Ruth Ann… I knew all the names, at least. There were thirty-five humans in the colony, with six of them gone on the raid, Jared included. Twenty-nine humans in the caves now, and one mostly unwelcome alien.

I also learned more about my neighbors.

Ian and Kyle shared the cave on my hallway with the two real doors propped over the entrance. Ian had begun bunking with Wes in another corridor in protest of my presence here, but he’d moved back after just two nights. The other nearby caves had also gone vacant for a while. Jeb told me the occupants were afraid of me, which made me laugh. Were twenty-nine rattlesnakes afraid of a lone field mouse?

Now Paige was back, next door, in the cave she shared with her partner, Andy, whose absence she mourned. Lily was with Heidi in the first cave, with the flowered sheets; Heath was in the second, with the duct-taped cardboard; and Trudy and Geoffrey were in the third, with a striped quilt. Reid and Violetta were one cave farther down the hall than mine, their privacy protected by a stained and threadbare oriental carpet.
