Eight years ago the December Plague swept through the human population of earth. The Infected were driven mad by the disease, becoming violent and cannibalistic, killing even those closest to them without hesitation.

Nella Rider, the court psychologist and Frank Courtlen a defense attorney are trying to establish the truth. But more depends on it than they know. They race to find the answers they need before the fragile remains of humanity vanish for good.
