Penric's Demon, by Lois McMaster Bujold
After ten years away, we are back to the world of The Curse of Chalion, Paladin of Souls and The Hallowed Hunt, with a novella about a young lordling who, much to his dismay, is possessed by a demon with several mature female personalities. It retreads some ground from the earlier books, but is basically a good read from one of my favourite writers, and will probably get one of my Best Novella nominations for next year's Hugos.
