@GreatwhiteNorth Unfortunately, they're pretty much meant to be read starting from the first as it follows Joe's life and times, family and job. The later one's may not make sense on some of the detail if you don't know the back story. His last one "Off the Grid" is the one with the grizz attack in it. Nate is his long time "outlaw" type friend, a master falconeer, who's on the run from the "G". His fav weapons are a .454 Casull and a .500WE. He's basically a good guy. Start with this one and see what you think. I also just read the "The Revenant", which was pretty good.
I read these decades ago:
Rocky Mountain Rendezvous: A History of The Fur Trade 1825 – 1840 - Fred Gowans
The Saga of Hugh Glass: Pirate, Pawnee, and Mountain Man - John Myers Myers
and this one a short while back:
Cowboys, Mountain Men, and Grizzly Bears: Fifty of the Grittiest Moments in the History of the Wild West - Matthew P. Mayo
I usually just get them from the library. I realize your local lib may not have much depth, but ask them if they have a "Inter Library Loan" program. Our's does and gets books for me from all over the state and college's as well.
