Beast Within, The-Villains, Book 2 by Serena Valentino

A cursed prince sits alone in a secluded castle. Few have seen him, but those who claim they have say his hair is wild and nails are sharp--like a beast's! But how did this prince, once jovial and beloved by the people, come to be a reclusive and bitter monster? And is it possible that he can ever find true love and break the curse that has been placed upon him?
