Farmer's son, Howie Ryder, becomes a hunted man after leaving for dead the officer who killed his family. Travelling through a rural landscape where humans are raised as livestock and people are tortured and mutilated in the most barbaric ways. Well written but grim. I don't recall anybody dying in a dignified manner.
There was also a sequel, "Dawn's Uncertain Light."
Great and underrated stuff from an author who got the unlucky job of providing the novelisation for Sly Stallone's megacrappy "Judge Dredd" movie.
