Melanie Hale is a devoted mother to her two children, a diligent caregiver to her ailing mother-in-law and a trusted neighbor in their wealthy Louisiana community. Above all, she's a loving partner to her wonderful husband, Collin.

Then there are the parts of herself that Mel keeps hidden. She's exhausted, worried and unfulfilled. So much so that one night, after a writers’ group meeting, Mel begins an affair with a successful local author named Luke. Suddenly she's transformed into a role she doesn't recognize―a woman who deceives with unseemly ease. A woman who might be capable of just about anything.

When Mel finds Luke’s dead body in his lavish rented house, she realizes just how high the stakes have become. Not only does she have to keep her affair a secret in order to preserve her marriage, but she desperately needs to avoid being implicated in Luke's death. But who would want to kill him? Who else in her life is keeping secrets? And most terrifying of all, how far will they―and she―go to keep those secrets hidden?
