My first thought: What does the title "Walk the Wire" have to do with this book? This was a typical Baldacci - a moderate length book but a really fast read. The main character, Amos Decker - a guy who had a football injury and now has perfect memory and associates colors with certain events and colors, is growing on me. He was such a non-communicator in earlier books that it was hard to empathize with him. I thought the hook-up between him, his partner Alex Jamison, and two characters from another of his series - Will Robie and Jessica Reel seemed fairly awkward. Just having the latter two around to save the lives of the first two periodically doesn't really add much to the story. Connecting a North Dakota fracking operation, Anabaptist communal farmers, a Russian spy, and ton of foreign mercenaries had to be hard to do - and the author only did a mediocre job of it. The whole story just kept getting more and more convoluted and the body count kept getting higher and higher. The final solution was so bizarre and came so far from left field that I couldn't even try to explain it. I decided I just and to accept it and move on. Certainly not one of David Baldacci's better books.
