Black Out by Lisa Unger

Annie Powers holds a dark secret that she would rather forget. Several years ago, she was Ophelia March, a young woman with no way out of a bad situation (precipitated by her mother's involvement with a serial killer on death row). Now, she's built a life in Florida with her husband, Gray, and young daughter, Victory. But memories are starting to flood back in her mind and someone seems to be following her. Can Annie be strong and conquer Ophelia's demons and finally overcome those who would hurt her and her family? While Lisa Unger's first two books, Beautiful Lies and Sliver of Truth, shared a main character, Black Out is a stand-alone woman-in-jeopardy novel, similar to but more complex than the books of Mary Higgins Clark and Circumstances Unknown by Jonellen Hecker.
