Ahhh! Someone else who actually reads Vorkosigan! I like the romance in that series in general... (Shards of Honor is one of my favorites.) I think I like them because the way the characters deal with romance is so much in line with who they are as a character (read Komarr and Civil Campaign). Sometimes in other series, it seems like once you add the romantic plot line, you can toss everything you know about that character out the window.
I have also read Uprooted, but I didn’t find it terribly memorable, so I can’t comment.
