Lois McMaster Bujold’s The Vor Game is another of the Miles Vorkosigan space opera books. They’re fun stuff, nothing dense, just a lot of crazy stuff happening. You know there’ll be ridiculous coincidences and that people will be brilliant just in the nick of time. You aren’t worrying about huge amounts of ethical implications, though the characters do a lot better job of being human than in some books I’ve read recently.
The thing about this one is that it felt like two books bolted together. There’s the arctic mystery story and then the rollicking space opera with Ensign Miles being very insubordinate. In the afterword McMaster Bujold talks about how they probably should have been split in two. I agree.
Executive summary: good light adventure fiction, like the rest of the series.
