Probably deserves four stars because it is a clever retelling of Cinderella. That said, my total enjoyment of it was almost three stars worth. I didn't really care for the main character nor, after a while, did I care about her unfortunate circumstances. At one point I was sort of hoping she'd die. Not the response the author was hoping for, I'm sure, but I'm not really your average female.
That said, I'm 95% positive every romance fan will love this book. So, check it out.
P.S. This is more like the T.V. show Revenge than it is like Cinderella, except not as good. Not by a long shot. Watch Revenge.
