I am hoping you can help me remember what series this is: post apocalyptic with a heroine who is (as I recall) some form of magic user. The beginning of the series starts when a 'demon' shows up at her house needing her help with something (sent by the old Lucifer himself, IIRC). In the process of the 'quest' he falls in love with her, and switches allegience to her, which is frowned upon, or outright forbidden.
The whole plot arc hinges around the daughter of her previous (late) girlfriend.
