I'm usually resentful of Novellas. I may give them a good rating, if I like the author well enough, but most of the time, a novella is too short. I like a meaty book I can sink my teeth into.Ember, on the other hand is the perfect length. I don't know if I'd call it a retelling of Cinderella, but it is definitely a REINVENTION of the tale. It's just so hard to describe why I liked this book so much. The main character wasn't all that likeable, to be honest. But the writing style and the world Ember lives in are fantastic! I will definitely be reading more of this author. Wow!PS- This book is FILLED with adult material. Lots of sex. Be warned.
