The national bestselling author of #HorrorBookTok sensation THE TROOP returns with a heart-pounding novel of terror about a young woman searching for her missing friend and uncovering a shocking truth.

On a sunny morning in June, Margaret Carpenter wakes up to find a new iPhone on her doorstep. She switches it on to find a text from her best friend, Charity Atwater. The problem is, Charity’s been missing for over a month. Most people in town --- even the police --- think she’s dead.

Margaret and Charity have been lifelong friends. They share everything, know the most intimate details about one another...except for the destructive secret hidden from them both. A secret that will trigger a chain of events ending in tragedy, bloodshed and death. And now Charity wants Margaret to know her story --- the real story. In a narrative that takes place over one feverish day, Margaret follows a series of increasingly disquieting breadcrumbs as she forges deeper into the mystery of her best friend --- a person she never truly knew at all.
