There are just some books that you read and don't enjoy, and you can't quite figure out why. This book was not of those. These are some very explicit reasons why this book grated on me:
1) The multiple narrators, which I usually like, did not work for this book. Thomas chose only a few of the characters perspectives, and it did not add to the book at all. I would have liked a third person narrative much better.
2) The last part of the book was rushed. The mystery was not solved completely. And the characters' ending did not feel complete in any way.
3) The characters fell in love way too quickly. This is going to sound funny, but the most plausible love story was the fresh-out-of-high-school story. I'm sorry, but falling in love in a few short days is not realistic in any sense; it's just fantasy and stupidity.
4) There were too many stories going on at once. It was the high school girl who got pregnant, and it was Sam's background, and it was Piper's love life, and it was Boone's disappearance. Too much in way too little time, and not enough was flushed out.
5) The mystery--which was the main part of the book--kind of got side-tracked and was not at all figured out.
So, that was my rant about why I did not like this book. I gave it 2 out of 5, and not 1 out of 5, because I liked the writing, and I'm a sucker for happy endings (which this one was).
So, that's my opinion on this book. I might try my luck with her next book. I won't swear off her permanently.
