At twenty-one years old, Oz Sullivan is unable to understand his fascination with and attraction to a much younger Adrienne Deschanel. Adrienne is spirited, passionate, and impulsive... all of the things Oz is not. Oz is drawn to her in a way that is inexplicable to him, and deeply concerning to those who know him. Amidst her father’s threats, Adrienne makes secret plans to run away with Oz. Before they can act on them, Adrienne and her family are involved in a tragic accident that takes the lives of the entire family. Adrienne’s body, however, is not found in the wreckage. Oz is devastated and unable to move on when an extensive investigation fails to solve the mystery of Adrienne’s vanishing. Three years later Oz has made a life for himself as an attorney at his family’s law firm. However, the predictability and peace of his quiet life is shattered when Adrienne is discovered, alive and well…but with no memory of anything before the accident. Oz is conflicted: grateful that she is alive but still damaged from her disappearance and hesitant to get involved and re-open a wound that never fully closed. Yet, Oz finds himself unable to resist helping when Adrienne’s desperate attempt to flee the confusing and dark influences in her life instinctively finds her on Oz’s doorstep. Unable to turn her away, but equally unable to get too involved, Oz keeps from her the truth of who he was and what they meant to each other before she disappeared. Against his better judgment he finds himself enmeshed in the mystery of what happened to her when she was sixteen. The more he learns, the less he understands, and as the story unfolds and Adrienne’s memory slowly returns, everything they thought they both knew gets called into question.
