What holds a strong and loving marriage together? Lies and secrets in a novel of twisting psychological suspense by a New York Times bestselling author.

Los Angeles homicide detective Dinah Marino may have a complicated relationship with her family, but her psychiatrist husband, Joe, makes her feel safe, secure, and happy. She couldn't want for a more loving or trusting man. But throughout their ten-year marriage, she's been keeping a secret from him--a secret she'd take to the grave.

Dr. Joe Marino loves his wife more than anything in this world, but there are things he's learned to keep close to the chest. When a missing woman tied to his wife's latest case is admitted to his hospital, doctor-patient confidentiality lands their marriage on some new and uneven ground.

As Dinah digs deeper into her case, tension works its way inside their picture-perfect home. Now the carefully constructed lies between them don't just simply threaten the delicate balance of their marriage--they could kill.
