When Martha Covington moves to Amberleen, Georgia, after her release from a psychiatric ward, she thinks her breakdown is behind her. A small town with a rich history, Amberleen feels like a fresh start. Taking a summer internship with the local historical society, Martha is tasked with gathering the stories of the Geechee residents of nearby Shell Heap Island, the descendants of slaves who have lived by their own traditions for the last three hundred years.

As Martha delves into her work, the voices she thought she left behind start whispering again, and she begins to doubt her recovery. When a grisly murder occurs, Martha finds herself at the center of a perfect storm—and she's the perfect suspect. Without a soul to vouch for her innocence or her sanity, Martha disappears into the wilderness, battling the pull of madness and struggling to piece together a supernatural puzzle of age-old resentments, broken promises, and cold-blooded murder. She finds an unexpected ally in a handsome young man fighting his own battles. With his help, Martha journeys through a terrifying labyrinth—to find the truth and clear her name, if she can survive to tell the tale.
