For those who are both fans of dark novels and films like Fight Club, you probably know Chuck Palahniuk. His new horror short story Guts sent a total of 67 people to the floor unconscious while he was reading the story to them. Crowded bookstore without enough breathing room? Probably.
You can read the odd story from Palahniuk himself.
The story is a part of the book Haunted. The cover should tell you something. I've read Fight Club. Now I'm tempted to start this one.
