Moonblood — Parley J. Cooper

House of Horror

From the moment she entered the monstrous gray chateau clinging to the cliffs above the churning Pacific, Vanessa was frightened. Why had her young husband -- so recently dead -- never mentioned the place where he was born? Or the cold-eyed aunt who offered Vanessa sanctuary until her baby was born? Were the other guests all mentally unbalanced, or was something more dreadful than insanity tormenting their minds?

Only after her son was born did Vanessa understand the evil surrounding her. She knew then that the ritual of moonblood would be practiced on her child!
