I'd actually give this three and a half stars. It wasn't bad, and I'm going to HAVE to read the 2nd book, Never Have I Ever, because the ending was such a cliffhanger. I didn't love the book though. Honestly, I would have liked at least some answers. Even a hint would have been nice. Toward the final third of the book, I thought I was starting to figure things out, but by the end, we were back to "everyone's a suspect". I feel a little jipped. That said, I enjoyed the book. It was a fast paced, easy read, and I'm a sucker for mystery and intrigue. This book definitely had both. The idea was original, and the perspectives it was told from were brilliant. I loved that the ghost of the dead sister (Sutton) was narrating and watching everything that was going on with the living sister (Emma), but that the living sister wasn't aware of any of it and had to sort it all out on her own. I also liked that the Sutton's death was a mystery even to her. When I began reading this book, I was under the impression that the Sutton was somehow communicating with the Emma; that they were working to solve the mystery together. That wasn't the case. They were trying to solve it independently, in a parallel fashion. 
 The things I disliked about the book have only to do with personal preference. I really don't like "mean girl" books, and this was definitely one. "The Lying Game" was a game that a group of popular girls (Sutton's friends) made up. It consisted of the girls planning and executing elaborate and often VERY cruel pranks. They had done so many horrible things, that even the police no longer believed their lies. They not only play these pranks on other people, but they play some of the cruelest ones on each other. Given the title of the book and and where the story is headed, it is obvious that Sutton's death has something to do with the game. I would say that this is ultimate "mean girl" behavior. I realize that there is a HUGE market for this kind of book, and teen girls that enjoyed Pretty Little Liars, Gossip Girl, or The Clique will love this as well. 
 A note of caution=> This book is NOT for tweens. I would say this is grade 8+. There is a "snuff film" that plays a prominent role in the plot line. I would expect that many teens aren't aware of what a snuff film is, but I am certain most tweens aren't.
