Wow! I rate this the best addition thus far to the Cork O'Connor series by William Kent Krueger: Terrific plotting (I will say nothing about the plot - you simply have the read the book; suffice to say that it gets going in a big way on page 1), with several clever twists and turns, including unexpected shifts in the basic direction of the story; great writing; excellent pacing. Actually, my only criticism is that the book, which is still a few hundred pages long, is too short - this is a novel I wanted to just go on and on. The plot will also help breathe further life into the entire series - it really does take things in a divergent direction. For the biggest bang, start the series from the beginning ("Iron Lake") - see www.stopyourekillingme.com
