Lucas Davenport ain't never going to be Harry Bosch, but he's a good enough morally ambivalent character that you care about what he does and why he does it. Of the Prey series, this is a standout for its plot about ugly sexual behavior in the sticks and for its detailed evocation of Minnesota in the dead (no pun intended) of winter. Mystery aficionados already know this book, and they'll tell you that another great thing about it is that Sandford plays fair with the plot. Things get strange, but there's a logical thread throughout. Superior reading for long-distance air travel.
