Under the Full Blooded Moon — Diane Saxon

Since he lost his father and his childhood at the age of ten to a witch's curse, cynical journalist Stuart Caldwell has searched the world in his quest to find the key to his family's centuries-old curse.

What he finds when he lands on the Scottish island of Breggar is far from what he expects. Instead of a battle to the death with the cruel enchantress he believes resides there, Stuart finds he's the one in the firing line, and the target is his heart.
