Two women struggle toward a dark truth as a killer avenges the sins of the past in a twisting novel of suspense by the USA Today bestselling author of Do No Harm, Behind Every Lie, and The Night Olivia Fell. After a violent home invasion, Neve Maguire returns with her daughter to Black Lake, her childhood summer home, hoping for a fresh start. But when the body of a woman is found floating among the reeds in the lake behind her house, she fears she has made a horrible mistake. Neve is hiding secrets, though. Detective Jess Lambert can tell. Recently back after her own personal tragedy, Jess knows what it's like to live with skeletons in your closet, and she's sure Neve has a few of her own. When another woman's body is found, Jess and Neve are forced to confront a horrible truth. Because one thing is clear: the darkness of the past is waiting. And the secrets of Black Lake are only just beginning to surface.
