I finished that up this morning. The novel now has the following:
Part One: 183 pages, which is 6 chapters totaling 45.750 words.
Part Two: 225 pages, which is 5 chapters totaling 56, 250 words.
Total: 408 pages, 11 chapters, totaling 102,000 words.
Looking backward, there's a lot of work yet to do. First of all, the chapters in Part Two are rather long, as can be seen from the number of words. I might try to break the chapters up a bit more, perhaps making the 5 chapters into 6, so it parallels Part One.
There's also a lot of rewriting I have to do in Part One, because right now the plotting has become inconsistent within the draft. I don't want to go into too many details, but in Part One the protagonist has dinner with her parents, and at the end of Part Two her parents are put into jeopardy. Well, as I wrote the book I realized that she's too estranged from her parents for their capture to be meaningful, so the person put in jeopardy at the end of Part Two is now her mentor. That means I need to remove her parents from Part One and give her mentor more of a role.
But...I can do that later. The advice I've received from everyone -- books, other writers, my wife, and my agent -- is to plow forward and get the first draft done. So even though some of the scenes in Part Three will be inconsistent with the stuff that currently exists in Part One, I'll write them anyway. After all, this is the most exciting part, the part that my character's arc has built up to -- and I can't wait to see how she gets out of it.
(I apologize if you find this discussion of plot too vague, but the other advice I'm listening to is this: Never talk out your plot with people in advance, or you'll lose the impetus to write the book.)
