Blood & Magic came about as a way to immortalize two characters from a roleplay I really enjoyed. The world is different and their personalities are a teensy bit different to fit their new setting, but they're pretty much the same characters. Although Lucille (based on a character that I had named Petula) is annoyed that I have a Petula in the novel that isn't quite so nice. I had to remind her, however, that she was going to be a villain, too, and probably would have if it hadn't been for Florian (Lorcan).
It's funny how some of my characters have more personality than people I know. They amuse me and vex me endlessly, but in the end they are the family I never had. My characters are real people to me so, of course, I feel for them. I get emotionally swept up in their problems. Like I said they are the family I never had. Although, I'm kind-of glad I don't have part-vampires and faeries in my bloodline. It might make things a little more complicated than they already are.
