Trust no one—unless he's the alien who couldn't shoot you.

A farm boy from rural Ohio—and an Other, alien consciousness in a human body, who couldn't kill Cassie after shooting her. His human side wins, and he defects to save her brother and, eventually, the world.
Cassie's high school crush, broken by running while looters killed his baby sister. Camp Haven renames him Zombie and aims him at the last humans—until he learns the truth, escapes, and becomes a resistance fighter and Sammy's protector.
