The Bookwoman's Last Fling by John Dunning (2006)

This was on the Lost Treasures shelf at my audio bookstore and since it was about a bookwoman, I just had to pick it up. At first I was distracted by the reader's voice, as he has done some of my favorite David Baldacci books, and it took a while to get into his new rough and tumble character Cliff Janeway. Janeway is a former cop, who is now running a used bookstore and is a specialist in old and rare books. He is called out to Idaho Falls to look at a very special private collection. Idaho Falls! I was just there this summer, proud to spend my one night in Idaho, the last state of the lower 48 that I had not yet visited. So I could visualize the farms, the Snake River. The main thing I remember was that it was very arid as I came in from the north, and then all of a sudden it became very green - irrigated by the Snake River. It wasn't clear if the horse pastures on the farm in the book somehow got enough water on their own or needed some irrigation.

I just looked up Cliff Janeway books in WorldCat - there are a whole slew of them, so I have another series to read.
