You don't mean "Black" do you, Navy? Ted Dekker wrote Black. But you might be talking about another book.
As far as Christian horror novels go, I'm not sure, because I've never read one, but as for horror films, I don't see how any film can be Christian and include such satanic things like are included in movies like Freddie VS. Jason, SAW, Hostel, and other movies which I refuse to watch due to their satanic images, mostly. If you have to include such graphic images as a person whose face is decaying and bleeding, constant disembowelment, blood, and gore, and scenes of half-naked zombie women then you odn't have a very good horror movie. Take a look a Stephen King's films. Some have a lot of adult content in them which totally ruins it, but the plots and entities are always such that no monster needs to be constantly having his flesh split open and blood seeping out. That's just sick!
