One tier down were the betas: the solid, reliable splice-and dicers, the gel-jocks, no award-winners here but no great backlog of malpractice suits either. They labored in the castles that had accreted around every source of front-line salvation. The assembly line wound through those fortifications like a perverse GI tract. The sick and the dying were swallowed at one end, passed through loops and coils of machinery that stabbed and sampled and doused them with the opposite of digestive enzymes: genes and chemicals that soaked the liquefying flesh to make it whole again.

The passage through salvation's bowels was an arduous one, eight days from ingestion to defecation. The line was long but not wide: economies of scale were hard to come by in the post-corporate landscape. Only a fraction of the afflicted would ever be immunized. But those lucky few owed their lives to the solid, unremarkable worker bees of the second tier.

And then there was Taka Ouellette, who could barely remember a time when she'd been a member of the hive. If it hadn't been for that one piece of decontamination protocol, carelessly applied, she might still be working the line in Boston. If not for that small slip Dave and Crys might still be alive. There was really no way of knowing for sure. There was only doubt, and what-if. And the fading memory of life as an endocrinologist, and a wife, and a mother.

Now she was just a foot soldier, patrolling the outlands with her hand-me-down mobile clinic and her cut-rate, stale-dated miracles. She hadn't been paid in months, but that was okay. The room and board was free, at least, and anyway she wouldn't be welcome back in Boston any time soon: she might be immune to ßehemoth but she could still carry it. That was okay too. This was enough to keep her busy. It was enough to keep her alive.

Finally, silently, the breathing corpse had been withdrawn from competition. Subsequent contenders hadn't rubbed her nose quite so deeply in her own ineffectuality. For the past few hours she'd been treating more tumors than plague victims. That was unusual, this far from a PMZ. Still, cancers could be excised. It was simple work, drone work. The kind of work she was good for.

So here she was, handing out raf-1 angiogenesis blockers and retrovirii in a blighted, wilting landscape where DNA itself was on the way out. There was some green out there, if you looked hard enough. It was springtime, after all. ßehemoth always died back a bit during the winter, gave the old tenants a chance to sprout and bloom each new year before coming back to throttle the competition. And Maine was about as far as you could get from the initial Pacific incursion without getting your feet wet. Go any further and you'd need a boat and a really good scrambler to keep the missiles off your back.
