When the stars go dark : a novel / Paula McLain.

Anna Hart is a seasoned missing persons detective in San Francisco with far too much knowledge of the darkest side of human nature. When unspeakable tragedy strikes her personal life, Anna, desperate and numb, flees to the Northern California village of Mendocino. She spent summers there as a child with her beloved grandparents, and now she believes it might be the only place left for her to heal. Yet the day she arrives, she learns a local teenage girl has gone missing. Anna is in no condition to become involved with the search--until a childhood friend, now the village sheriff, pleads for her help. Then, just days later, a twelve-year-old girl is abducted from her home. The crimes feel frighteningly reminiscent of the most crucial time in Anna's childhood, when a string of unsolved murders touched Mendocino. 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 these missing girls, she must learn that true courage means getting out of her own way and learning to let others in.
