• The World According To Dutch and Tales from a Dirt Road by Dutch Mantel are both great
  
• Swimming with Piranhas: Surviving the Politics of Professional Wrestling by Howard Brody - not a wrestler, but a prolific promoter and former NWA President
  
• The Professional Wrestler In The World Of Sports-Entertainment and The Somebody Obession by Matt Murphy are really good to give insight into the business in the indies.
