When tragedy strikes her personal life, Anna, desperate and numb, flees to the Northern California village of Mendocino to grieve. She lived there as a child with her beloved foster parents, and now she believes it might be the only place left for her. Yet the day she arrives, she learns that a local teenage girl has gone missing.

The crime feels frighteningly reminiscent of the most crucial time in Anna's childhood, when the unsolved murder of a young girl touched Mendocino and changed the community forever. As past and present collide, Anna realizes that she has been led to this moment. The most difficult lessons of her life have given her insight into how victims come into contact with violent predators. As Anna becomes obsessed with saving the missing girl, she must accept that true courage means getting out of her own way and learning to let others in.
