"I know where I want to go. If only someone thought of giving me a roadmap."
Eighteen-year-old Hendrix Williams is a self-diagnosed sociopath and aspiring serial killer, and his biggest nuisance is his fellow coworker and almost-friend, Michelle "Arden" Campbell. The night after their high school graduation, Arden shows up at Hendrix's door and demands they escape their dismal, small-town life.
While Arden is just looking for someone who might finally understand her, Hendrix views this impromptu road trip as the perfect opportunity to find his first human victim. But Arden's brutal honesty and adventurous spirit only drives Hendrix closer and closer to madness. Navigating through a world that has rejected both of them, the two alienated teens crash in motel rooms, meet fellow travelers both intimidating and heartfelt, and keep secrets from each other that will rip their lives apart.
