Darius Anah, 17, lives with his mother and younger sister, Mahlah, in a city where every major milestone—known as a Life Event—is dictated by The Book of Zalmon. The teens’ father was a Leaver, someone who took off for the Town Beyond, past the forest surrounding Zalmon, which is a source of great shame—and also temptation—for Darius. The government justifies its control of the citizens by claims that it promotes “equal opportunity and liberty.” Instead of a Natural Death, which is presented as deeply traumatic, people spend their last days before their assigned death dates at a facility called Quiet End. Physical affection is restricted to “conception duties.” Despite this intrusion, there are rumors of an Underground world. One day at work, Darius peeks at his boss’ account at Central Processing, hoping to see whether his crush might be his Life Match. When he looks up Mahlah’s life partner, he’s horrified to learn she’s been assigned an imminent death date. Darius spirals out of control as he attempts to save her life and, in the process, discovers a shocking web of dark secrets. The narrative beautifully combines dystopian elements with a moving story of love, grief, and defiance. The engaging, evocative writing builds suspense and develops characters in ways that will keep readers invested. Main characters are cued white.
