This book is hilarious, entertaining, and interesting all at once. It's a humorous story about an intrepid little (literally) man who is bumbling his way through space. I've never read a humorous space opera that was so much fun, and yet serious. It's the first story in the Vorkosigan Saga that features Miles Vorkosigan himself, and I hope it sets the tone for the series.
Miles, a deformed scion of the impressive Vorkosigan line, must not only deal with his physical disability, but the attitudes of the Spartan-like society that his house is important in as well. I really enjoyed how he fared in his intergalactic adventures, each step trying to correct some mistake or help some unfortunately soul, only to get himself righted in the end.
If Miles wasn't so self-deprecating, his genius and natural mental abilities might make him insufferable, but instead, I end up rooting for him through the whole story. I don't know how Bujold does it, but she even makes the story of a sociopath sad and makes me weep for a former torturer. Well done.
