Full Moon — Jennifer St. Clair

Werewolves change into wolves when the moon is full. But Edward's curse only allows him to be *human* when the moon is full.

Alone and despairing, Edward hides himself away from the world and scrapes out a meager existence for almost a century amidst the forest he has grown to love. But in the depths of a terrible winter, he stumbles across clues from the life his mother left behind in Faerie, and the truth of both his birthright and his curse.
