Growing up in the dark tourism capital of the United States, sixteen-year-old Olive should be comfortable with death. But ever since an allergic reaction almost sent her to the wrong side of the grass, she’s been terrified that there is no afterlife. And after the death of her surrogate grandmother, Olive has kept everyone at arm’s length because if there’s Nothing after we die, relationships and love can only end in sorrow.
When she summons a spirit to answer her questions about death, Olive meets Jay, a hitchhiking ghost trapped in the woods behind the poorhouse where he died. Olive agrees to help Jay find his unmarked grave in exchange for answers about the other side and what comes next.
Meanwhile, someone―or something―is targeting Olive’s classmates, and the longer Jay lingers, the more serious the attacks become. Blaming herself for having brought Jay back, Olive teams up with maybe-nemesis, maybe-crush Maren, ex-best friend Davis, and new girl Vanessa to free Jay’s spirit before he’s trapped as a malevolent shade and the attacks turn deadly. But in doing so, Olive must face her fear of death and risk losing another person she loves to the Nothing.
