All of us fell silent at that, even George. Maggie’s hands stilled, dropping away from the dog. The distant beeping of the computers, the occasional squeal or bark from a lab animal, and the footsteps of the other technicians provided a strange sort of background music. Joe looked between the humans and let out a resonant, echoing bark.

Dr. Abbey reached down to pat him on the head. “Well, since we’ve obviously got a lot to talk about, why don’t you come to my office? There’s cookies and tea, and I can tell you all about how I’ve managed to pervert the laws of nature. Come on, Joe.” Waving for the rest of us to follow, she walked forward, into the bustling lab.

“Are we going with her?” asked Alaric.

“Got a better idea?”

“Nope,” he said, glumly.

“All right, then. Following the crazy lady to our deaths it is.” I shrugged and walked after her, trying to look nonchalant. The day was getting more interesting by the minute. I just had to hope it was the sort of interesting we’d live to talk about later.

The nature of the so-called reservoir conditions has never been fully explained, although a great many theories have been proposed, some reasonable, some not. Why does the KA virus manifest its live state in certain parts of the body? Why does that live virus then fail to spread the infection according to the laws that govern all of its other manifestations? Why is retinal KA most common in females, while cerebro-spinal is most common in males? Nobody really seems to have a clue.

We do know that reservoir conditions are becoming more common, with reported cases of retinal, cerebro-spinal, ovarian, testicular, and pituitary KA in both human and animal hosts up by more than eighteen percent overthe last eleven years. There are rumors of new reservoir conditions manifesting themselves, conditions with scary names like “cardiac” and “pulmonary.” Yet still, no one knows why.

Taken all together, it’s enough to make one question whether we truly dodged the end of the human race… or merely delayed it by a decade or two.

Dr. Abbey’s “office” was a euphemistically named cubicle only slightly larger than the ones around it. It didn’t help that it was jammed with file boxes, outmoded computer equipment, and—best of all—clear plastic tanks full of assorted insects and arachnids. I don’t have a problem with spiders. Spiders can’t carry Kellis-Amberlee. Ditto giant hissing cockroaches and squiggly things with way too many legs. Becks didn’t share my disregard. Every time the squiggly thing moved, she sank farther back into her chair.

It’s called a millipede, said George.

“It’s called comedy,” I muttered, and turned my attention back to Dr. Abbey.
