Turns the series from a western into a spy thriller. For my taste, this one relied a bit too much on events happening in other books. I did not remember everything a clearly as I would have to. Also, a lot of the 'resolution' is projected into future work. Clearly meant to open up the rather small scope of the last books into something more akin to the world-transforming first books, this felt a little forced and let me put down the book a few times.
