Horror stories don't have to be about blood and gore. Read some of Dean Koontz's books for example. I found this about writing horror from one of the old masters, H.P. Lovecraft. Very interesting. Hope it helps you out. I read good horror all the time.
As some of you may know, I enjoy creative writing. Most of my work is kind of fantasy/adventure but I recently had an idea for a horror story. As a newbie to the genre, do you have any tips for me?
