6: Portrait of a 21st Century Snuff Fighter — G. Wells Taylor

Is he the explosive and dangerous result of illegal genetic experiments gone terribly wrong or a Darwinian throwback spawned by global warming, pollution and radioactivity?
You ask him! Join the world's most violent man on a raunchy voyage of self-discovery that takes him from the snowy peaks of the Canadian Rockies to the blood-soaked Snuff Fighting rings of Argentina.
6 is a horribly funny and terrifying story of the near future. First and last in the Gene Spiral Series of books, 6 - Portrait of a 21st Century Snuff Fighter will have you screaming for more.
