I decided to set a target of 70,000 words for this novel. It’s an arbitrary number — I don’t care if it goes significantly longer or shorter. 70,000 words seems like a good length for an urban fantasy caper novel.
The outline is still working well for me. I know where I need to go. And it does not preclude improvisation — I came up with an ending for the scene I’m working on that fits quite nicely. It isn’t in the outline, and it doesn’t throw the outline off either.
