This is an ideal book to read if you're looking for a dark, engrossing retelling of Cinderella. 
 The characters are deep and engrossing, and I like how Iris, Ruth, and Clara are all equally likable and unlikable in their own ways. I could relate to all three of them wonderfully, particularly Iris always getting the short end of the stick and Clara's struggle with her traumatizing life as a shut-in. Casper and Iris' love story was also very moving and likable. 
 The writing itself is VERY strong and any reader would be hard-pressed not to have a handful of strikingly beautiful quotes to store up after finishing this book. 
 Raw and beautiful, although being an adult novel, it's fairly appropriate for younger readers as well, with the exception of a few innuendoes and implications, including but not strictly limited to, a scene of implied rape. 
 Highly recommended.
