Spent the last couple days editing the manuscript of the documentary book.
The publisher suggested shortening all the chapter and section headings. My co-author and I spent a day shortening and in some cases writing new headings.
We were able to reduce the wordage by about 50%. The result is, as the publisher promised, easier to read.
Now to transfer the new headings to the manuscript and get final OK from my co-author.
Lesson for future--concise chapter and section headings!
