"Unpredictable, unputdownable, and unlike anything you've read before."--Liane Moriarty "Ingenious. . . . Arresting. . . . Keeps you puzzled and intrigued, right until the end."--New York Times Book Review She's a wife. She's a mother. She isn't who you think she is. Nicki Clements has secrets, just like anybody else--secrets she keeps from her children, from her husband, from everyone who knows her. Secrets she shares with only one person: a stranger she's never seen. A person whose voice she's never heard. And then Nicki is arrested for murder. The murder of a man she doesn't know. As a pair of husband-and-wife detectives investigate her every word, as the media circle like sharks, all Nicki's secrets are laid bare--illusions and deceptions that she has maintained for years. And even the truth might not be enough to save her. For although Nicki isn't guilty of homicide, she's far from innocent. . . . For fans of The Girl on the Train, Gone Girl, and the best of Hitchcock comes an extraordinary thriller--and an extraordinarily unreliable narrator--from an author whose work has been described by Tana French as "like watching a nightmare come to life."
