Fight Club

Where can I start with this book? I'll admit I saw the movie about 10 times before I even knew the book existed (shame on me!) but the depth of the characters goes far beyond what the movie shows. It really made me contemplate capitalism, religion and society in general from a completely different point of view. Fortunately, I'm an only child and not a middle child, otherwise I would've ended a bit traumatized!
Regardless the plot, I can't say that there's much difference with the movie, but you can enjoy both very much, even if you know how the story ends.
