This wasn't really my type of book. I didn't like the characters (guess you weren't supposed to) but I suppose what I mean is that I didn't care either way what happened to them.
I didn't think it was a very well written book, perhaps the concept/ideas etc were more important. I read it, so it wasn't bad but I didn't enjoy it and didn't really get anything from it.
It felt a bit gimmicky. I only really read it because everyone keeps saying they movie was good. Maybe it is, maybe it is better. I like reading the book first though, but since doing that I doubt I'll be wasting my time on the movie.
