1. Charlaine Harris
I always thought of her Southern Vampire Mysteries as lighthearted fun, not horror fiction. But they've been turned into the extremely dark True Blood show on HBO. And unlike the vampires of Twilight, hers actually do bite, instead of mooning about all the time.
2. Francesca Lia Block
Not a "horror author," but many of her works feature very dark, disturbing themes.
3. Ramsey Campbell
A British horror author that kindergoths might not have heard of. My favorite book by him is "The Long Lost."
4. Douglas Clegg
I can't remember which one I was reading, but a Douglas Clegg novel grossed me out so much, I put it down and never read another book of his again. (That's a compliment though, but it means I'm a gore wimp!)
5. Nancy A. Collins
Probably most known, so far, for her Sonja Blue books. Check out her awesome taste in music, which you can discover on MySpace.
6. Storm Constantine
Best known for her "Wraeththu" series.
7. Nancy Kilpatrick
A prolific Canadian author. Of all my Facebook acquaintance friends, hers are the most interesting, thoughtful real, and honest updates. I end up paying more attention to them than to updates from people I know more closely, and that surprises me. She writes and edits a lot of vampire fiction, and wrote the extremely popular Goth Bible. She also stays extremely busy editing and contributing to short story compilations and anthologies.
8. Brian Lumley
British author, best known in our scene for the Necroscope series.
9. Yvonne Navarro
"Back in the day," when the net.horror scene was small, I had the pleasure of corresponding occasionally with this nice and creative lady. I even got to meet her at a World Horror Con in Eugene, Oregon. I am so delighted to see her success in the horror field!
10. Clive Barker
I hardly need to introduce him to you guys. Seriously. But here are some links!
11. Laurell K. Hamilton
Author of the extremely popular "Anita Blake: Vampire Hunter" series.
12. Neil Gaiman
Oh for heaven's sake, you already know who this is!
13. Dean Koontz
Currently writing some interesting Frankenstein-based fiction.
