Hullo Doctor!
Dracula meets Trainspotting sounds like a good call. Vampires need to get all sordid and grimy again, I reckon. Are you going to do the Scots dialect thing, like Irvine Welsh? Or set it as a series of interconnected mini-stories?
Well, you can find my novelette "The Talented Man" on Amazon (and everywhere else) for free, so you don't even have to pay. (Security contractor, Kieron Rose, tries to hold it together in a run-down Cairo mansion on the border between worlds. Cultists, looted antiquities, supernatural forces, the whole nine yards...)
The sequel, "Eventide", is out in the wild too. (Set in London and following Rose's dodgy former colleague, Holden, as he tries to atone for his past and survive against the odds. Victorian occultists, Egyptian-revival temples, revenants roaming the underground and evil spirits in the night...)
