From the New York Times bestselling author of Orphan X and comics in the Batman, Wolverine, and Punisher universes comes this relentlessly thrilling adventure perfect for fans of The Walking Dead and The 5th Wave. A Hollywood screenwriter, developer, and producer (V, The Book of Henry, Black Flags), Gregg Hurwitz brings his cinematic flair to this suspenseful new tale.

In one terrifying night, the peaceful community of Creek's Cause turns into a war zone. No one under the age of eighteen 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 eighteen--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.
