Mostly the movie follows the book. About the biggest difference is that Amy's narrative interweaves with Nick's right from the beginning, whereas in the film that only really happens halfway through. The ending was more fully realized in the novel - it felt like the film kinda rushed it. And Desi's role is bigger in the film.
Overall, I actually liked the novel more, but mostly because you get a fuller picture of what everyone is thinking, since they are narrating. Although, I did like better in the movie how you were left wondering whether or not Nick was guilty much longer.
I've never been a book person, which is a shame because there's so many I'd love to give a chance. I'm literarily ignorant.

DEADMAN'S ROAD by Joe R. Lansdale - it's a collection of stories featuring Lansdale's bad-ass preacher character, Reverend Jebediah Mercer. I LOVE me some 'Weird West'!
HUNTER by James Byron Huggins - Sylvester Stallone acquired the movie rights for this one some time back. Apparently, it's a straight-up, action / horror tale which reads like 'Rambo meets Predator' - SOLD! At one point, Sly was gonna use this book as the basis for the screenplay for RAMBO 5 - luckily, that didn't happen but it may come to pass as a separate movie. Either way, I'm looking forward to devouring this book!
