One year after divorcing renowned defense attorney Julian Cross, Cassandra Hartley discovers that her entire marriage was built on lies—starting with the sapphire necklace he claimed she stole, which he actually gave to his pregnant girlfriend six months before their split. But when a professor's book reveals Julian's secret journal entries expressing obsessive devotion to Cassandra throughout their marriage, she's forced to question everything she thought she knew about the man who destroyed her wrongful death case against her mother's killer. Now Julian's girlfriend is feeding Cassandra information that unravels not just her marriage, but her entire family history, while the one woman who knows what really happened the night her mother died watches from the shadows. As twisted revelations pile up and loyalties shift, Cassandra must decide who's been playing whom—and whether the man who forced her to absolve a murderer was protecting her or destroying her all along. Some obsessions look like love until you see them in the light.
