One for Sorrow

Me neither. I mean, I know that writing a tie-in novel is different from writing fanfic. With fanfic you don't submit your idea to the people who own the series, and you don't have to follow any pattern you want. So yeah, writing a tie-in novel obviously has the consent of the people who own the series. But artistically the main difference is just who the intended audience is and things like that. It's not like writing fanfic is *less* creative than writing tie-in novels. Sometimes it's far more creative.
