Good libri and movies????

I need help finding some good books, tv shows, o Film about licantropi (obviously), and heres what i'm looking for: the main character needs to be a werewolf, and he/she can't be searching for a cure, and he/she has to be able to shift at will, not being forced to change at the full moon, I'd like it to be a romance with horror. So basically I'm looking for a book o movie o tv mostra like Teen lupo
