Gentleman Jole and the Red Queen

Well, it is not a typical Vorkosigan novel, there is no Big Crisis of any kind, just a pair of people trying to get on with their lives after losing someone they loved. But I got to finally revisit Codrelia and Sergyar, got to know Oliver Jole and met a bunch of secondary characters I want to know more about.
Definitely book for long-time fans, but there is nothing wrong with that.
