Bride of Satan

From the author's blog:

"Vicious was the original name of a novel the publisher gave the schlocky title Bride of Satan. The story has to do with murders surrounding the filming of a sequel to the famous Anthony Winterroth shocker 'Vicious.' A man who loves horror films is assigned to cover the filming even as his girlfriend, whose parents were slaughtered by a real-life maniac, prepares an article attacking the film. And what about that demon with the four-fingered claw?"
