The first young adult page-turner from New York Times bestselling author Gregg Hurwitz

In one terrifying night, the peaceful community of Creek's Cause turns into a war zone. No one under the age of 18 is safe. Chance Rain and his older brother, Patrick, have already fended off multiple attacks from infected adults by the time they arrive at the school where other young survivors are hiding.

Most of the kids they know have been dragged away by once-trusted adults who are now ferocious, inhuman beings. The parasite that transformed them takes hold after people turn 18 --- and Patrick's birthday is only a few days away.

Determined to save Patrick's life and the lives of the remaining kids, the brothers embark on a mission to uncover the truth about the parasites --- and what they find is horrifying. Battling an enemy not of this earth, Chance and Patrick become humanity's only hope for salvation.

Audiobook available, narrated by Todd Haberkorn.
