Let me just start with: Awesome.
This is the first book in Jim C. Hines' Princess series, featuring a Cinderelle, Snow White, and Sleeping Beauty who will have you completely rethinking your Disney versions. These ladies are based on their original prototypes--that is to say, Cinderella (Danielle) can talk to birds, and Snow White's (Snow!--don't ask her if you can call her by her real name!) nemesis is her own mother, not a stepmother. And you probably know what happened to Sleeping Beauty (Talia).
I was beyond impressed with this. It's fast-paced, funny, and interesting, without losing sight of the characters and giving all three of these girls a lot more depth that they usually get. If you haven't read it, please give yourself the opportunity to enjoy it!
Jim C. Hines also has a blog that's great reading.
