Seventh Night

Born of a succubus and fathered by a man, Rurik will do anything to be a true demon and be accepted in the lower reaches of Hell. When his mother comes to him on the seventh night-the night when all demons fly to the living world to wreak havoc-he is excited about his assignment to defile a woman. He goes forth with high hopes, having been taught how to seduce and anxious to test his training. But when he catches sight of a beautiful woman suffering a nightmare in her bed, he is easily distracted.
Her pliant body responds to his tempting touch. Her mind allows him in. He finds himself wanting her instead of the woman he has been assigned to defile.
