No real specifics, they're open to discussion. Some possibilities - the young woman summons a demon (on purpose or by accident) and ends up having to live with it. As for the werewolf line - maybe a young woman is savagely bitten by a rogue wolf and then found by a pack alpha. He has to help her through her change and becoming a wolf. Or a female wolf is part of a corrupt, abusive pack with a rabid alpha. She manages to escape and fine another alpha, and they have to deal with the other pack together?
