This is about a girl who is kidnapped. Each chapter is told either by her mother, the detective or her kidnapper. It is mildly reminiscent of Gone Girl in that each chapter is told by a different person, and that it flashes back and forth to "before" and "after" her kidnapping.
Some felt that there were a lot of inconsistencies in the book, both in the details and in the characters. Mia was manipulative and did the whole thing to punish her father. Some felt that the flipping around in time was confusing and others felt it was patronizing to have the 'beginning' and 'after' at the beginning of each chapter.
