I feel a little guilty for not liking this more. I think the basic premise--a retelling of the Cinderella story where Cinderella is enchanted at birth to always be obedient--is brilliant. I enjoyed the character of Ella, although she was the only person in the novel that was even close to multi-dimensional. The romance was good, the writing was good, and the world-building was good.
What was missing was the emotional impact. Ella was never in any real danger, and, maybe because this was intended to be a light-hearted fairy tale, or maybe because everyone knows how Cinderella ends, I was never worried that things wouldn't turn out fabulously for her.
Oh, I DID love that Ella was her own hero, though, that she was the one who was strong enough to save herself (and all of Kyrria!). The romance wasn't the be-all, end-all of the book, and the prince didn't have to come to the rescue, and I appreciated that, yea verily.
