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.

Endangered by CJ Box

The latest in the Joe Pickett series and doesn't disappoint.

The Pale House by Luke McCallin

This is the second book in the Gregor Reinhardt series. It's even better than the first book, The Man From Berlin. The story has advanced from May 1943 to the spring of 1945, but it is still set in Yugoslavia. Reinhardt is now part of the feldjager korps, a kind of super unit of the German military police, created to help maintain discipline in the Wehrmact as the Third Reich crumbled.

McCallin has written that these two books are part of a trilogy, and I can't wait till the third installment.
