I liked this book, actually rather more than I usually like the Reacher tales. The fights were still part of the story, but it was a story that contained fights, not a series of fights strung together by a story.
I don't know if Childs is moving in a different direction with Reacher or if this was a one off, but either way, I enjoyed it.
Great job in describing Wyoming and the Western mentality. He included a number of details and reactions that are common to the area and often missed by writers who have not spent much time in the Rockies and their surrounding land.
