Well, last night's work consisted of merging chapters 4 and 8 into a new chapter 4, which was easier than I had feared it would be, and moving what was chapter 7 to be chapter 5 and giving it a tighten. So this issue's kind of on my mind at the moment. (The underlying issue is that I have a book where the last half is OK, the first quarter is OK, and the bit from 25% to 50% of the way through really sags badly for two of the viewpoints. The third viewpoint, which those two do not meet until well after the 50% mark, is good throughout, but in compressing the sag out and reshaping the chapters for the other two, I have to compress that thread too in order not to break my structure.)
