The novel is a prequel to the main series, so rather than following Jack as drifter/man-of-action, this focuses on him in the last few years of his career as a Major in the United States Military Police Corps. The novel begins with Jack receiving a medal and being rewarded by being sent to a professional development course, one with only three students (the others being a CIA and FBI agent) and is actually a cover for a mission that seems nearly impossible.
A transaction of a hundred million dollars has been picked up in chatter in Germany, and with a cost that high, it can't be for anything good, so the trio begins work on tracking down an American seller of something they don't know as quickly as possible.
The novel was actually a lot fun, and although I do prefer the man-against-the-world approach that Reacher takes in most of his adventures, seeing him in action as part of a team was a nice departure. A solid read and definitely one that will keep me waiting for the next.
