Oh, I am so glad you are enjoying the series. I've tried to get so many people to read it! Some people just say, eh, space opera not my thing, and other are confused because Bujold didn't write the books in order. But the series is excellent.

And not only is there a new book out now, but Bujold is apparently working on an Ivan-centric book! Set after Diplomatic Immunity but before Cryoburn.
