If a book has a blurb by Stephen King proclaiming it as the "best horror novel of the new century", I'm buying it. The author is Scott Smith, whose previous book "A Simple Plan" was turned into a very good movie.

I haven't read the previous book (but I've now added it to my todo-list), but the movie and this book both share a similar concept: Take an intriguing premise and follow it realistically to its logical endpoint. Sounds simple, but it isn't. Much of fiction is ruined by the reader going "WTF is he doing that, is he braindead?" at one or more of the characters. In this book, I can't really see anything I would've done differently had I been one of the characters.

I don't want to say anything about the plot since it would just ruin the experience for anyone who has not read it yet. Simply put, if you want a book you can't put down you need to buy this book.
