When Laurel Estabrook is attacked while out riding her bike one Sunday afternoon, her life is changed forever. She begins work at a shelter for the homeless and there meets Bobbie Crocker, a man with a history of mental illness and a box full of photos he won't let anyone see. When Bobbie dies suddenly, Laurel discovers that he was once a successful photographer, and her fascination with his former life begins to merge into obsession, not least because some of the photos are of the very same forest trail where she was attacked and nearly killed. Laurel becomes convinced that his photos reveal a deeply hidden, dark family secret. Her search for the truth leads her further from her own life and into a cat-and-mouse game with pursuers who claim they want to save her.
