I feel like I have to stick up for authors like Tessa Dare and Theresa Romain (whom I'm currently reading). Tessa is one of my favorite historical romance authors, and I just read my first by Theresa Romain and would rate it a "B". I will freely admit that they are basically modern romances with modern sensibilities and some historical window dressing, but that doesn't lessen my enjoyment of them at all. I know it's a fairy tale, and I don't care.
I don't usually rec those types, since I know that many of you prefer the more traditional historicals, but I'll be sure to note that they are quite mistorical if I do happen to mention one.
