This certainly caught my eye. Normally I shy away from vampire like stories but this one somehow kept my attention. Now I'm looking forward to more.
This seems like a a crossover with something I've read in the past. It's almost like a Warhammer story. Shadow World maybe?
I'm curious as to how long it will be before Umbridge kicks Harry out of his private room. (If she does that, she is risking a very painful death...)
