Becky Morgan has a life most women would envy until a car accident lands her in the hospital. She insists she's fine, but it quickly becomes clear she's changed. She's forgetful, paranoid, short-tempered. Her husband wants to write off her change in personality to the IVF hormones she's taking in an attempt to get pregnant. Becky's best friend, Jules Dalton, is a gorgeous, single woman, with a habit of sabotaging relationships. When Jules loses the man who could have been "the one," she confronts the realization that being adopted at birth is contributing to her trust issues. She's obsessed with finding out why she was given up and turns to DNA testing in hopes her matches will lead to her birth parents. As Jules dives into her DNA results, Becky's life soon becomes one she doesn't recognize. Those closest to her are accusing her of things she simply can't explain or remember. She's terrified of losing everything: her career, her marriage, and her dream of becoming a mother. Desperate to put the pieces of her shattered life back together, Becky needs her best friend more than ever. What she doesn't realize is that Jules knows something that could explain everything away. Becky has a dark past she's unaware of. A darkness that's coming for her. It could also get her killed.
