You Should Have Known: Now on HBO as the Limited Series The Undoing

In this "smart and devious" New York Times bestselling thriller, a marriage counselor's relationship begins to unravel when the mother of her son's classmate is murdered (The New York Times). The inspiration for the HBO series The Undoing, starring Nicole Kidman and Hugh Grant.

Grace Reinhart Sachs is living her best life. Devoted to her husband, a pediatric oncologist at a major cancer hospital, their young son Henry, and the patients she sees in her therapy practice, her days are full of familiar things. Grace is also the author of a book You Should Have Known, in which she cautions women to really hear what men are trying to tell them.

But weeks before the book is published a chasm opens in her own life: a violent death, a missing husband, and, in the place of a man Grace thought she knew, only an ongoing chain of terrible revelations, leading her to dismantle her life in order to create a new one, lest she allow these disasters to destroy her.
