One night three years ago, the Tanner sisters disappeared: fifteen-year-old Cass and seventeen-year-old Emma. Three years later, Cass returns, without her sister Emma. Her story is one of kidnapping and betrayal, of a mysterious island where the two were held. But to forensic psychiatrist Dr. Abby Winter, something doesn't add up. Looking deep within this dysfunctional family Dr. Winter uncovers a life where boundaries were violated and a narcissistic parent held sway. And where one sister's return might just be the beginning of the crime.

Bestselling author Wendy Walker returns with another winning psychological thriller, Emma in the Night.
