Third that I've read in the Vorkosigan series by Lois McMaster Bujold...
This time Miles finds himself all mixed up in a huge political plot on Cetaganda. The Barrayaran political set-up I understand, it isn't anything like what we have in the States, but I get it. The Cetagandan one on the other hand... it is seriously screwy. There's women who are never seen, women that everyone acts like can't be seen, men in military power but only through their wives... it's very odd.
Miles of course gets himself stuck right in the middle of everything as is his habit. I'm never quite sure if he's right to go out on his own or if it would have been better if he'd told his superiors what was going on from the get go.
This one focuses more on the Barrayaran characters than any of the Dendarii, I think Miles gets to be Lord Miles though the whole thing actually, no Admiral.
