I loved this story.  Indeed, once I started it, I didn't want to put it down.  It was a charming, romantic retelling of the Beauty and The Beast story set in Regency England.  Louisa, an heiress, was an ugly duckling who wanted someone to care for her, not her fortune.  Her parents had passed and she was living with her grandfather who wanted her to be married.  Douglas, a vampire with a conscience, was a loner in the extreme.  He was living in a cave with no interaction with others besides what he physically needed to survive. He had his own inner demons to fight as he was guilt-ridden from an incident early in his life.  The day Louisa stumbled upon Douglas' cave was a life-changing event for both of them.  Karen skillfully used their interplay of words to develop their relationship.  There were a few other characters and scenes interspersed in the story but most of the story took place in the cave.  I enjoyed this book very much.  I was very happy with the ending and actually came away from the book feeling as if I'd learned a valuable lesson from it.  Bottomline:  This is a feel good book that I'd highly recommend to anyone who loves romance and/or adult fairy tales.
