If the first thing you're thinking is "Fight Club has a book?", the answer is yes. Chuck Palahnuik's debut book became an instant classic, having a story that many of you already know, but is still one of the best twist stories there are. Better than any Shyamalan movie.
The first thing you have to know about the book is that it has some pretty rough language, but, of course, you're not going to read a book about underground fight clubs expecing gentlemanly language. The most notable thing about the book is the disturbing content it has in some parts, for example, the narrator's tongue gets cut in half because of a pounding he gets.
The book's theme isn't really about fighting, as much as it is about the society we have. We're people expecting to become something: rockstars, millionaires, expecting to be remembered for something. The book actually speaks for itself:
"You are not a beautiful and unique snowflake. You are the same decaying organic matter as everyone else..."
If you're in a mood to get existentialist or just to get an angsty attitude, this book is for you. Sure, the content can be a bit strong, as it has even influenced people to do things a normal person wouldn't even think of, but if you don't read the book or see the movie, then you're missing out on a lot.
Also, if you're a new author and would like your book to get reviewed by me, then just send it to me and I'll try to post a review as quickly as I can.
