After sharing a draft with a number of people over the summer I have received quite a few suggestions. Some touch on topics that need to be added or expanded. Work needs to be done to improve the visual quality of the graphs. Overall the suggestions lead to a better narrative structure. See the new outline. The total word count of the first draft was roughly 20,000 words. The final version will be about 30,000 words. Still a short book.
Now targeting completion and trial printing of a new draft by the end of 2022.
