Still troubled by an ambush that leaves his deputy lingering near death, Sheriff Cork O'Conner must investigate the mutilation murder of a Chicago businessman. Soon, Cork finds himself distracted by the lovely female shadowing him and the handsome man stalking his wife.
This series takes place in Upper Minnesota's "Arrow Head Region." For those readers who like outdoor stories with Native American folklore weaved into well-written mysteries. Several of the books are focused on and in the Boundary Waters on the US Canadian Border. Known as a famous outdoor camping, canoe, and fishing region.

Additional Series with some of the same outdoor adventure flavor.
C.J. Box The Joe Pickett Series. Wyoming Game Warden. 24 books series. Again, read in order if you can.
In my opinion, the books are far better than the recent TV series, especially if you are interested in Game Wardens and their daily jobs.

Paul Doiron, The Mike Bowditch Maine Game Warden. 15 books in the series. Again, read in order if you can.
Good, fast-moving adventures. Mike is a younger single Maine Warden. Who work in different regions of Maine's outdoors. Including some of the Atlantic Coastal regions. A small heads-up. As a single character, he has "encounters" with several girlfriends. Some of the text can be sexually saucy. But no worse than you can see on TV. If you are sharing the books with younger readers...take note.
