This book is set in the Vorkosigan universe, about 200 years before the main action re Miles Vorkosigan. I haven't read any of the others, but I really like the way that Lois McMaster Bujold writes. It reminds me alot of Elizabeth Moon, who is one of my very favorite writers. I intend to get a hold of more of McMaster Bujolds books.
Really good story, really well written. A nice sunny afternoon read (if you read like I do) or a nice Sunday read (if you read like a human.)
