Fight Club, by Chuck Palahniuk
If you have an older teen / young adult who doesn't love reading, try this. I promise. - Anne Marie (Mom of an 18 year old who said "I didn't say I loved it, but it liked it a lot. It wasn't torture.")
The first rule about fight club is you don't talk about fight club.
Chuck Palahniuk showed himself to be his generation’s most visionary satirist in this, his first book. Fight Club’s estranged narrator leaves his lackluster job when he comes under the thrall of Tyler Durden, an enigmatic young man who holds secret after-hours boxing matches in the basements of bars. There, two men fight "as long as they have to." This is a gloriously original work that exposes the darkness at the core of our modern world.
