Regency Romance meets Beauty and the Beast

Regency romance novels are a genre where the ending is always a given, and the authors of these books are running out of stories to spin. They can be enjoyable for a quick, easy read if they are well-written. From the very short sample given (only half of the pages in the First Look were the actual story), I believe I would like this book. I am reminded of Beauty and the Beast from the synopsis, but instead of saving her father, the heroine in this tale must rescue her sister from a lifetime bound to a horrible Earl.
