The Bear and the Dragon by Tom Clancy

Team Yankee by Harold Coyle

Quag Keep by Andre Norton

The Choir Boys by Joseph Wambaugh

East of Eden by James Steinbeck

The Three Musketeers by Alexander Dumas

The Sun Also Rises by Ernest Hemingway

The Inferno by Dante

any of the books Elmore Leonard has written but look at Get Shorty, BE Cool, and Rum Punch. all have been made into movies but the plot twists better in the books.

The Light at the End by John Skipp & Craig Spector
One of the best horror/vampire novels ever written. Puts Salem's Lot to shame.

The Getaway by Jim Thompson

Shoot the Piano Player by David Goodis

Angels and Demons by Dan Brown

The Odyssey & The Illiad by Homer

Anything by Joe R Lansdale take a look at A Fine Dark Line and any of the Hap & Leonard adventures

If you get a chance read some of Andrew Vachss'
Burke novels. Blossom is the first of many. He has a new book out now Two Trains Running and it is a great book.

The Dark Knight Returns by Frank Miller
I know this is a graphic novel but seeing Batman beat up on Superman is classic

A must read by all wrestlers.
Vision Quest by Terry Davis
Read this in high school a few years before the movie came out. I remember living on Nutrament during wrestling season.

I could list books all day. Two years ago I started a journal of all the books I read. Yes I read that much.
