Yes, I LOVE that book. I haven't loved any of Patrice Kindl's other books quite as much, but I keep reading them because I loved Anna's story so much. Retreating into secret passageways in the walls of a house! Becoming a sort of house sprite, fixing utilities and baking cookies and sewing things! Falling in love with a guy from a single letter (which is both kind of hilarious and strangely sweet)!

I made a post about it a while ago, actually: The Woman in the Wall (http://osprey-archer.livejournal.com/224003.html).
