Andrea/Cara here, thinking about how delightfully magical it is when actual history confirms an author’s fanciful imagination! See this amazing artifact—I will explain in a moment. But first, a brief preface . . .
Although I write fiction, and am allowed to take artistic license and make things up when my plot requires it, I feel very strongly about creating an accurate Regency world for my make-believe characters. I try to get all the little details right, from manners and titles, to fashion and food, and all the other elements of daily life. And when actual events are part of the story, I do a lot of background reading to make sure I stick to the facts. (Granted within those events, I let my characters create their own reality.)
