I semi-recently read Jo Walton's Longbourn. It's Pride and Prejudice from the point of view of the servants, and quite excellent though the narrative takes an unexpected swing, in the third quarter of the book, into a graphic account of how much, precisely, it sucked to be a footsoldier in the Napoleonic wars. So be braced for that if you read it.

My Real Children sounds very interesting and I'm adding it to the to-be-read pile.
