Blood Hollow by William Kent Krueger

 Book 4 in the Cork O'Connor series. I didn't have a post for this but I know I've read it.

Boundary Waters by William Kent Krueger

 A Cork O'Connor mystery/adventure story. In this one, O'Connor searches in the wilderness near the Canadian border (Lake Superior) for a girl named Shiloh who, it turns out, is being hunted by some bad men. It's a bit formulaic but well done nonetheless. This is a good series.

Purgatory Ridge by William Kent Krueger

Third installment in the Cork O'Connor series. Every entry has been solid.

Boundary Waters by William Kent Krueger

Second installment in the Cork O'Connor series. Just as good as the first entry.

Iron Lake by William Kent Krueger

Mystery/thriller series concerning ex-Sheriff Cork O'Connor in Minnesota. Like in the series by Bryan Gruley or Steve Hamilton, or the Joe Pickett series by C.J. Box, the protagonist is a relatively ordinary guy (no Jack Reacher or James Bond) with integrity trying to do the right thing in a corrupt world. Excellent start and I'm looking forward to the rest of the series.
