I gave this book, four stars because it wasn't great, but it wasn't bad either.
As Ms. Coulter states on the back of the book, this is a rewritten story. I'm almost tempted to see if I can find the original Lord Harry's Folly to see what has been changed, but I'm afraid it'll change the way I think of the characters.
Hetty (Henrietta) is like no other heroine that I've ever read, and it isn't because she has become "Lord Harry" either. She has formulated a plan of revenge that she has no intention of backing down from. Even when it appears that she might lose her life in a duel!
I don't know that much about Jason, the Marques of Oberlon. I don't want to give away parts of the book, but I don't know what else to tell you about Jason. He had been married to a bitch. And given the circumstances of her death, he left England for awhile. When he was in Italy, it appears he had quite a few flings.
Now he's back. He doesn't hate women. He has a mistress, but he's not a womanizer. I think that he has a tendency to be domineering, but Henry wont let him.
Lord Harry's adventures are as outrageous as Ms. Coulter promises!
This book may not be a "must" read, but if you pick it up, I don't think you will be disappointed.
