Day 27: The most surprising plot twist or ending...

 

Fight Club by Chuck Palahniuk

 

This is the only book I could think of that made me say "What the fuck?!" out loud. I mean, aside from yelling it in anger at a TSTL heroine. I couldn't believe it. I'm pretty sure my brain started dribbling out of my nose, I was completely shocked. And I tried to come up with another book, but I can't think of any that are so mind-boggling as Fight Club.
