In the middle of Book 3 there are four chapters that just do not flow with the rest of the story. Everything before them is great. Everything after them is great. But these four chapters are as rough as 24 CAMI sandpaper.
The biggest problem is those four chapters, all on their own, tell a fascinating story. Not only that, the last third or so of the book is built on what happens there. So, it's not just something I could easily cut out.
The only recourse is to fix the chapters. I have already revised these chapters the most compared to any other portion of Book 3. That leaves me two choices. 1) Just continue to polish away at what I have or 2) Start over from scratch. It's a big job either way.
At this moment, I'm unsure of which is the best coarse of action. Maybe I'll have some clarity by tomorrow.
