Book of a Thousand Days - Shannon Hale

I have a soft spot for fairy tales. My mom owned one I stumbled across and read several times as a child, and I love reading about the history and origins and such. This was based on a lesser known Grimm tale, and I love 95% of what she's done with it. Even the other 5% was enjoyable, it just stuck out a bit when her medieval Mongolian characters behaved a little too 20th Century American (getting down on one knee to propose, for example). Very sweet, highly recommend.
