Completely unbelievable, ridiculously over the top, but still a lot of fun. I worried that a teenage protagonist might bore me to death, but it was unfounded. Miles is a gung-ho adventurer in the old space opera pulp fic style, and that he is so young is only incidental. It's good to read and get carried along for the ride. The world-building remains interesting, and I look forward to experiencing more of the universe the Vorkosigans play in.
