I have "Prey"; "Hunted" and the prequel "Watcher in the Woods". The entire Mountain Main and Last Mountain Man series. All of the Ashes books, The Rig Warrior set, the "Codename" set (there are only four of them) and I think all of his horror novels, except maybe one. The one set I don't have that I am still looking for are the Blood Bond series. It's also a western but I am not sure how many books are in it, it's so very hard to get his stuff used.
The only books I didn't much care for are the new westerns he's doing.. The Last Gunfighter. But you know, I figure I like everything else... LOL.
I am a huge fan of his and I would not be at all surprised if he lurked FR. I would love to see some form of his common sense government come into action.
