Tim Powers writes historical... fantasy? Horror? He writes alternate histories as they should have happened if we lived in a world of the supernatural. He writes histories that show how much less unlikely history would seem if only we were allowed to explain things through the supernatural. He... Oh, my point? Right. Hide me Among the Graves. Once again we have muse/vampires, like in The Stress of Her Regard. Only this time they're up against a bunch of Rosettis, a veterinarian, and an adventuress. And they're running around a sort of London as Dickens might have written about if he were paid by the idea instead of by the word. Good stuff.
