If you are a fan of James Patterson's thrillers then this is one of his better ones. If you are a fan of psychological thrillers you will be doubly blessed. The storyline is well crafted and has way more twists and turns than usual. The ending is a surprise, although you sort of see it coming in the last 20 pages or so. If you are squeamish about young kids be psychologically abused, you may want to take a pass.
