I’m gonna second the Necroscope series. It’s engaging, disturbing, and extremely graphic. (I mean how it describes things) Just the first few pages made me wanna barf. XD It’s a really good set of stories though, dealing with Russian vampires. You gotta check it. It’s got that whole heavy epic feel to it.
One of my fave vampire trilogy is The Black Castle by Les Daniels. It takes place during the Spanish Inquisition, where a rather hardcore vampire is, himself, completely disgusted by the Inquisition. The story centers around him, the guy who wrote the Malleus Malifecarum, and a crazy girl he rescues and turns into a vampire…The story from the first book is really unique, but sadly, it pretty much repeats itself in the later books, only in different time periods. :/ Still, if you enjoy the first book, you’ll love the others, they’re as fun as the first, only not so original.
If you want some really…messed up but extremely wonderful books, check out The Book of Shadows by James Reece, and The Book of the Mad by Tanith Lee. These aren’t about vampires…so much. I guess they can be described as fantasy/goth/horror? But I think you might enjoy them. Shadows is about a girl who becomes a witch, has sex with ghosts…and…yeah. I can’t describe this. Lol, but it rocks. And when I mean a witch, I don’t mean no Harry Potter business, I mean it’s inspired by sixteenth century witchcraft.
Mad is a set of several stories that eventually tie in with each other. It’s completely crazy, and includes freaky bird people, a psychotic mental asylum and some guy who might be a vampire…
These are far from your requests, but they certainly do disturb, and include all sorts of paranormal stuff that still seems freaky in what is essentially a dark fantasy setting.
If you like nineteenth and early twentieth century vampire and ghost literature, look up some of these cool writers; Sheridan Le Fanu. He wrote the classic Carmilla, which served as influence to Bram Stoker. Lots of ghost stories, too.
John Polidori wrote the ever famous The Vampyre, which I thought was damn creepy. He wrote a lot of Goth romance shit, too.
Algernon Blackwood, who I know for his short stories, has many a great ghost story. They’re all real traditional too, so if you like classic ghosts, this guy’s for you.
Erm but wait a minute. I remmeber speaking with someone on Fluther about all these artists before, and that person was a fan. And I think it was you lol. So I don’t need to tell you any of this. Was it you? I can’t remember. If it wasn’t, I have more to list.
