"So, how long has my mother had this questionable fetish for bisexual Barrayaran admirals? I don’t think even the Betans have earrings for that one." [loc. 4825]
Three years have passed since the death of Aral Vorkosigan. His wife Cordelia, being Cordelia, has not resigned herself to a faded life of mourning: she is Vicereine of Sergyar (the planet where the two first met, back in Shards of Honour) and is pursuing a number of projects. One of these involves Admiral Oliver Jole, who has appeared -- fleetingly -- as Aral Vorkosigan's aide in several previous novels, and is now revealed to have been Aral's lover for many years, in a polyamorous relationship which shivered to pieces after Aral's death. Cordelia and Jole have remained close friends, though, and at the beginning of Gentleman Jole and the Red Queen Cordelia returns from Barrayar with a freezer-case full of genetic material and a very interesting offer for Jole.
This novel focusses on Cordelia and Jole's renegotiation of their relationship, and of their lives. Jole is about to celebrate his fiftieth birthday: Cordelia is in her seventies (though Betan lifespans are typically well over a century): they have both lived full and worthy lives, and they have both grieved the same man. Now, perhaps, it's time for a change of direction.
Which is obviously when Miles and Ekaterin and their six children show up.
I find I don't have a great deal to say about this novel, though I enjoyed it immensely. My first great crush on the Vorkosigan Saga is two decades in the past: I was only vaguely aware that Aral had died, since I haven't read the last couple of novels in the sequence. But I returned to Cordelia like an old friend; I'm saddened by the death of Aral; and I am quietly pleased that he had Jole, as well as Cordelia. (In the early books it was clear that, while bisexual, he preferred men: Cordelia was the exception, because she was nothing like a typical Barrayaran wife.)
I'm happy, too, that characters past the first flush of youth are written as romantic and sexual beings; that they communicate well with one another, rather than having the kind of difficulty that comes from mutual incomprehension and is so common in flimsier romantic fiction; and that Betan technology gives Jole a chance at parenthood with the person he loved.
I strongly recommend Foz Meadows' post on this novel, which I found fascinating -- not least because it references a work of fan fiction which could be seen as predictive -- and which also has a comment from Bujold.
