My internal editor: winner and still champion!
I'm about 142 pages into my WIP when it suddenly occurs to me that I'm off course. I've got too many characters, my heroine (who's supposed to be the woman in jeopardy) is practically sitting in the backseat of this story, and my hero's big, dark back story secret is being eclipsed by another big, dark back story secret that was supposed to be just a passing thing.
So okay. I surrender. I've got to go back about three chapters, excise two characters (who I really liked, dang it!), move up a murder that I didn't have happening quite so soon, create a secondary character to be a stronger red herring suspect in the crimes at the heart of the story, and oh yeah, gotta put my heroine in escalating danger.
NaNoWriMo, I hardly knew ye...
