I'm writing the last chapters of the book! Not the last chapters, but it's looking like I have 12-ish left. They're approx 1.5k on average, so I'm definitely in the range of less than 20k to complete the book.
I am taking a lot of time with this ending, but that's because if you don't like the end to book 3, you're not going to like the series overall. Book 3 is basically the whole point of writing these. :)
I'm really happy with the chapters I'm completing right now, so while I'm not pleased with spending, what, 6+ months on a single story, I am very proud of this book. Juggling the perspectives, the number of characters, and the political elements has improved my skill as a writer, I think. I look forward to more complex stories and challenges like the Human Omega books have been for me.
I also look forward to having fewer viewpoint characters, lol.
Anyway! I'm confident the book finishes in two weeks or less. I do a lot of improvisation, so if I hit another twisty road I could be knocked back. But I write a little bit out of order and a lot of the ending chapters have already been completed. I'm hitting areas of paved road in front of me.
And then editing won't take longer than two weeks. I've been editing during the times that I'm stuck. Spending months on this draft has also improved the continuity of the story, so I won't have to rewrite chapters. I may delete some chapters, but I won't need to do book surgery, thank god.
Hang in there a little longer! I'm working on my process to avoid burnout and increase efficiency in the future.
No chapter this time :<
