When 26-year-old Emy Monroe returns to her small Nebraska hometown to babysit her four-year-old niece, Hannah, she expects a quiet night of wine and nostalgia with her childhood best friend. Instead, she wakes in the middle of the night to an open window, an empty bed, and the gut-wrenching realization that Hannah is gone. As the only adult in the house—and with a history of poor decisions—Emy quickly becomes the prime suspect.

Desperate to prove her innocence, Emy uncovers unsettling links to a previous abduction in a nearby town—a little girl found dead six days after her disappearance. When she learns her sister, Chloe, has been receiving threatening messages from a stalker obsessed with her and Hannah, the investigation takes a terrifying turn. As her father, the county sheriff, lies unconscious in the hospital after a suspicious car crash, Emy races to unravel the stalker’s identity.

But the deeper she digs, the more tangled the truth becomes—and the more she begins to suspect that her own family’s secrets may be at the heart of Hannah’s disappearance.
