Kathy Hunt came to Castlemoor when she got the news of her brother's sudden and tragic death. The shadow of Castlemoor fell ominously across the moors. Every soul seemed to live in terror. When Kathy found that her brother's life work - a study of bloody, primitive rites, once performed on these very moors - had disappeared, she vowed to find the manuscript and complete his book. But strange forces blocked her search. Edward Clark, the dark, handsome man who claimed to love her, assured her the danger was real and malevolent. Then she realized that the old fiendish rites were being reenacted... she was in the center of a circle of death... the intended sacrifice in a diabolical ceremony.
