The worst thing in writing something for someone else, and I've found this several times over the years, especially in movies, is where you talk to an editor or an executive and you think that you're talking about the same thing. Then you go away and do what you thought you were talking about and hand it in and find that you were quite wrong, and while you were describing (say) a romantic comedy with ghosts in they were buying a scary ghost story with perhaps some love in, and nobody is happy and the project is doomed.This is why HarperCollins isn't publishing The Arrangement. It's taken me a long time to figure that out.
I'm not certain what they thought they were buying -- I think maybe a sexy threesome romantic comedy with some ethnic people in. Which is very much not what I wrote. Although my book does have a threesome, and sex, and romance, and ethnic people.
