Ah, that moment when the subject matter experts return the draft, and you stare at the unopened emails, taking a deep breath…
When 3 out of 4 say in different way but with the same meaning “You didn’t show this; you need to tied up that plot thread with a scene to explain”… well, then, I have a missing chapter.
So first I enter all the corrections I agree with, or sit back and think about “It’s not that I’m precisely wrong in what happened, as I failed to foreshadow that the character was mistaken, and then underscore their realization, so how do I do that?”
And then, having fixed everything else, use that to define the shape of the hole that still has to be filled in, and the things that are in there. Sort of outlining the story so far, to figure out structurally what goes there. (See? I do plot! When stuck. But only the things I’ve already written.)
And then, with a half a clue and a lot of winging it, I get stuck in…
Only to realize this is going to be at least two chapters.
Think brain, think! There’s beta readers waiting impatiently! Make with the words!
