"The first rule of fight club is don't talk about fight club. The second rule of fight club is don't talk about fight club."
The narrator starts out as a middle aged completely average guy. He has a decent job, unmarried, nice condo, and hates his life. The only thing that is different is that he has a horrible case of insomnia. The only thing that helps him is to go to different types of support groups, pretending that he has the affliction of every support group he attends. The story starts when he meets Marla, another woman that is also pretending and both know it because they go to several of the same support groups. Marla goes because Marla feels alive when she goes to meetings all about the dying. The narrator ends up meeting Tyler and the two of them become friends and move in together after the narrator's place blows up. The two start a fight club to feel alive, with Tyler as the face of fight club. Most of the book is about the fight club and the change that the narrator goes through because of Tyler, Marla, and fighter.
I loved the book. I didn't see the twist at the end coming. It starts at the end and goes back through the story until it ends at where it started. The book is violent and is kind of graphic. It describes the different injuries that occur during fight club. Easy to read and keeps your attention.
