The 'Dark Duet' series should have just been one book. This second book didn't offer anything new and should have just been the ending of the first book. The steamy scenes were hot, but I just couldn't appreciate this as a book on it's own. I thought that there would be a twist, but there wasn't. Exactly what you thought would happen after reading the first book IS what happens. I felt like this was a waste of my time.
