Catherine Bomarzini returns to the family castle in Italy after her father’s death and gets caught in the web of a mysterious love triangle: a man who is at times repulsive, at others enchanting; and a creature of the night whose gentle eyes and touch reveal his infinitive love and devotion. With the help of Martha, her faithful childhood nanny, and the ghost of a slain young girl, Catherine discovers the medieval curse that threatens their lives and only she can dispel.
