Sinful - Charlotte Featherstone

Oh my this was my catnip. Hero is very flawed and overall horrible human being with a deep, dark secret. Heroine is born of the "lower" classes and not attractive who reforms and falls in love with him. What I got, was good until the last couple of chapters. That was, WTF??!!
Granted, there is an epilogue, not included in this book, presumably available SOMEWHERE online. I looked for it and got taken to a webpage for hair loss (once it was translated- thanks Google translator!).
The only positive for me, was the book's originality.
