And it's about Cordelia! Squeee!
This is what I get for not opening Goodreads every day: I miss important announcements like this!
She doesn't say much, does she? Let the speculation begin! I, for one will be delighted to get back inside Cordelia's headspace, particularly if the book is set after Cryoburn. But, really, at any point in the timeline.
If you have no idea what I'm talking about, go read Cordelia's Honor (which is the two novels, Shards of Honor and Barrayar published together.) And never mind the blurb on Goodreads, it tells you nothing useful about the plot (to be fair, it's a difficult plot to summarize succinctly!). (I wrote a Very Long Post about Lois McMaster Bujold if you want more convincing to try her books.) Cordelia is just one of the best female protagonists I've ever read, and you deserve to get to know her.
