After a flu pandemic, a man with a terminal illness becomes one of the few survivors in a transformed world: "Fast-moving, violent, and vividly imagined." —David Poyer, USA Today–bestselling author of Hunter Killer

Diagnosed with Huntington's disease as a child, Kade never expected to live very long. He passed his time learning survival skills that would come in handy during a large-scale catastrophe, but didn't think he'd actually make use of them. Then, when Kade has reached his twenties, the United States is ravaged by the Feline Flu—which soon hits pandemic levels.

In desperation, a vaccine is rushed out to the public—but it only makes thing worse. It deprives its recipients of their higher functions, leaving them with only their primal urges. The resulting bloodthirsty monsters are known as foamers. And as the world around him descends into the Primal Age, Kade finds that he is expected to lead other survivors in an unrelenting fight for their lives, forced to redefine humanity in a world without law . . .

"A worthy addition to the canon of postapocalyptic fiction . . . like the best of such books, at its heart it's a frontier novel, brutal and exciting." —Tim McLoughlin, author of Heart of the Old Country
