Pretty good thriller. It kept me entertained. Basically it was the story of three girls who had been abducted and tortured many years before and then escaped. They had to then relive their horror and find new info and insight into their captor to keep him from being paroled. It had a few twists and turns the major one I didn't expect in the end kept it from being 3 stars. It wasn't as dark or morbid as the blurbs and other reviews make it seem. It's pretty pg-13 which is fine but I think it was trying to ride off the Gone Girl success. Over all decent book that kept me interested.
