Nope. But from what I'm hearing, it is different than the book. First of all, they aged Jonas to 16 instead of 12 (because the love interest would be more believable than if he stayed 12). However, I still thought it was pretty good just as a movie. I mean, I'm sure there's a bunch of stuff I'm missing having not read the book, but there weren't like... giant gaps of information that aren't there- atleast from what I can tell.
