My full review is here on my personal website. I'll post a few excerpts here, though:

4.0 out of 5.0 stars

The very worst thing about this book is that it is yet another twist on Cinderella.

The very best thing about this book is how interesting the twist is. A perfectly obedient child that rebels as best as she can until she finally breaks the hold of the curse. I’ve seen the movie countless times (and love it) so I was expecting the characters to be a bit older, but I’m thrilled with the book and, naturally, I love it more than the movie. Except for the music. This book didn’t come with an awesome soundtrack like the movie. O_o
