If we're talking about literature with ties to wrestling, check out John Irving, the same fella who wrote _The Cider House Rules_, _The World According to Garp_, and _A Prayer for Owen Meany_ (the movie version was called "Simon Birch").

Irving taught for several years at the University of Iowa's Writer's Workshop MFA program. While he was up there, he rolled around with Gable and several other big names from the 70s. He ties a lot of wrestling in with his writing and it's good stuff.
