I was expecting more from this novel after having read Room, but can only say it was a disappointment. While the story was original and had potential, it was wasted on pages of inane dialogue and a thin plot with an unconvincing twist at the end. 
 None of the characters were given much of a back story. Instead the author decided to give us bits and pieces of the characters' past lives, scattered throughout the story, in an attempt to keep up the suspense, but it was not paced well and ended up being more frustrating than anything. It is revealed in the beginning that one of the main characters, Jenny, is murdered. The rest of the book is a flip flop between the events of that night and present day in which Blanche (Jenny's recent BFF and on the run from her lover) tries to figure out who done it. Problem is, Jenny was the most interesting character in the book...and now she's dead. 
 A few events in the very last pages of the book meant to shock but were only a disappointment as they pandered towards the reader's suspicions and obliterated any credibility that any of the main characters had. 
 There were some interesting pieces to this book; they just weren't put together very well.
