I got the book back from my editor a few days ago, and I am about halfway through Chapter 3 right now with edits! It's going really well; my editor is really thorough, as always.
The highlights you can see here are all things I've either changed, added, or moved, based on feedback. (This particular section was a bit rough. It reads so much better now.) In any case, I want to touch base once a week with an edit update until this beast is finished!
There's 34 chapters total. So, at midway through chapter 3, I'm about 9% through. Unless anything changes, I should be a good deal further by the time I check in next monday!
