Ay yi yi. I have reached a point where I'm totally confused by own manuscript! There are so many alterations and notes, and it's been so long since I was last at this point, I'm not sure exactly what I was thinking.
So what am I going to do?
I call it "stripping the manuscript." I'm going to take out anything that was to be moved or deleted from the first draft to complete the second draft, then I'm going to print it and start reading from the beginning. Hopefully when I reach this point again, I'll beore aware of what's missing and when things should happen, and then I can go back and add it. This means I'm looking at at least four drafts now - the first, the second "stripped" draft, the third where I put in what's missing and the final fourth.
This doesn't mean there won't be a fifth or even sixth draft. It just means there will be four for sure.
But this is the best way I can think of to figure out just what the heck is supposed to happen and when in the last third of the book.
