It isn't a particularly new trend, but it seems to be growing in popularity. While paranormal romances and fantasy fiction have soared, it seems as if the paranormal is finding its way into the historical. I'm not talking about the Pride and Prejudice Zombie thing which is parody and not really a true blend of genre. I'm more interested in books such as Suzanna Clarke's Jonahtan Strange & Mr. Norell or Amanda Grange's Mr. Darcy, Vampyre.
Why is this popular? Any thoughts? I think this is a trend which will grown more into the mainstream of historical fiction and historical romance. Will it help or hinder these markets? Will it become a more solid sub-genre? I'm not even going to go into Steampunk which I think is poised for an explosion and I think it is worthy of its own post. But do you agree there is a growing trend?
As a historical writer, are you open to adding paranormal elements to your writing? As a reader, is this violating the purity of the genre?
