I think it would be interesting to have a hero or heroine who is both straight-laced and wild. How fun is that? Think, the naughty librarian. How about a woman who is addicted to porn (by herself) and is caught (extremely unlikely and I wouldn't write that, but . . .)? The unusual may not be very close to real life, but it would certainly be memorable and it would leave your reader with something more to worry about.
DEVIL OR ANGEL, original recording, 1956, by The Clovers
I want to know if you're a devil or angel. The ms. I'm working on now is all about a devil or angel. I got my inspiration not from the song, but from one of our own great and famous authors, Linda Thomas-Sundstrom. Nobody writes this type of character better.
