My Roman historical romance, "Flavia's Secret", has no paranormal elements, but vampires were already sexy and seductive in the classical world. The ancient Greeks knew of a ghost-like creature called Lamia, who seduced young men and sucked their blood. Cute!
And who would be a husband in medieval Europe? There, a wife or partner might 'inspire' their lover by serving a meal laced with ground-up earthworms!
Best wishes, Lindsay
