To my amazing wife's chagrin and to my surprise, I'm a horror writer. Looking back, I can't really say how that happened or when. I remember, as a 6-year-old, being so terrified of the movie Poltergeist that I was scarred for life. Ghostbusters had me terrified to go into my parents' back bathroom for fear that the Library Ghost would be waiting for me (NOTE: I have also never figured out why I thought the Library Ghost would haunt my parents' bathroom). I can even remember, as a child, the first time the horror of death really struck me (it was while I was watching Superman II). So I was a pretty sensitive kid who pretty much avoided everything horror, and I'm not sure when things changed.
By the time I was in high school, I was working on a series about a kid who saw monsters everywhere and set out to kill them. The first book--the very first one I ever completed--was about him stalking a poor town doctor that had the misfortune of looking like a vampire (read the first chapter). The story was played for laughs, but looking back, there were elements of horror in it, so sometime around there I started delving into the darker side of things, but it wasn't until recently that I went full on horror.
The thing is that, even as a kid, the idea of horror fascinated me, even if it scared the crap out of me at the same time. There is something incredibly cathartic about facing fears and coming out victor in the end. There is something inspiring about watching people struggle against Hell. Whether they succeed or not seems less important than the fact that they struggle. In spite of all the odds and the dangers and the pressing darkness and the betrayals, they keep fighting.
And then there's just the fact that monsters are cool. But that's a topic for another day.
