Winterfair Gifts first debuted in a genre romance anthology called Irresistible Forces, but I'd only recommend it to those already familiar with the Vorkosigan stories, as it doesn't stand on its own very well. While not an indispensable entry in Bujold's long-running Vorkosigan series, this novella was a very satisfying read, one of those rare stories that left me with warm fuzzies after the story's conclusion.
Taking place between A Civil Affair and Diplomatic Immunity, plot is secondary in this story. This is a trait shared with some of the other recent Vorkosigan books, but this isn't a gripe. People read Bujold for her characters, which are second to none. With more than two dozen Vorkosigan stories available, Miles Vorkosigan, his family, and comrades have all become like friends to this reader. Every new Vorkosigan story is a welcome chance to visit with these longtime friends again.
