First, let's start with the good. This was an excellent fractured fairy tale. I liked how the absurd idea that only one woman would be able to fit the shoe was played at least partly for laughs, and the relationship between the sisters was a nice touch.
Now for the bad. This book could really have used an editor. Holy misspellings, Batman were there mistakes! It really tore one from the otherwise good story. There was also one continuity error at the end which was also quite jarring and distracted me from the rest of the story.
