Romanian unification is on the horizon and the spirited Crown Princess of Carpathia, Caroline, would prefer to ride horses and archery to embroidery and dancing. Complicating her life is her recent discovery that she's a witch.
Prince Stefan Sigmaringen travels to Carpathia to meet Caroline. He discovers he has much in common with her. He also learns that a strange man, Timon, has an unnatural interest in him.
Upon Stefan's engagement, he overhears his mother confessing to a horrible secret – she cursed him in order to conceive him and Stefan will become a werewolf when he turns eighteen. There is a condition to overcome the curse, but it will require Stefan to draw on all his inner strength and Caroline, her courage. Can they break the foul enchantment and secure their future or will Stefan give himself over to the lupine curse that haunts his family?
