These were recommended by a friend @BooktalkBmth, if you are looking for Non Fluffy Vampires (R) you could try:
- The Vampire Quintet by Jasper Kent (period Russian vampires, I think I'll give this one a go)
- The Strain by Guillemo del Toro
- A Discovery of Witches by Deborah Harkness
Have you read Night Watch by Sergei Lukyanenko?
The fantasy encylopedia article on vampires hasn't been updated in a while but you might find something there you haven't read
if you find any more, let me know too.....
