In 12 weeks, 17-year-old Paul Ledger will be dead. At least he hopes so. Paul is trapped in the worst cult the United States has ever seen. Infected with a zombie virus, symptoms culminate in a dead body but thriving mind over a course of twelve weeks. If he doesn't earn the final death he longs for, he'll be chained in a basement facility, moaning for human flesh for eternity.
Days slip through Paul's graying fingers. Humanity faces the end. His brother has the virus and is dying, too. Paul's hopes ride on Heather's genetic code. Her immunity leaves her unchanged and untouchable. What would she see in the zombie he was becoming anyway? Dominic's army of infected grows, capturing the south and leaving little alive in its wake. While Paul and his friends work on the vaccine, protecting the north becomes protecting the world. Heather is taken hostage and Paul races toward Dominic to save his heart.
Time is running out and Paul's original wish for death looms. As his skin grays and hunger becomes uncontrollable, the world burns. Heather and Paul have fallen for each other, but with life and death barricading them apart and the potential cure disappearing into time, they have no hope. Paul's hunger is all-consuming. He has to walk into the flames, join Dominic, or eat everyone he loves. Can he save anyone, if not himself?
