Just finished Gun, with Occasional Music.
This is one of those books that has some clever ideas, a somewhat interesting story line, but part way through goes in a radically different direction. Sometimes that is good. In this case, it was bad. It felt like the author backed himself into a corner and wasn’t sure where to go with the story line.
Regardless, the twist at the end was interesting, and the author’s non-traditional views of what might happen in the future were fun to think about.
