I just emailed the final draft to the book designer, who will start the process of layout, designing the look of each page, in the next few days.
I am very excited to have the book reach this stage. Still working on final touches to cover art and design. Also: what’s called “front matter,” that is, all the stuff that comes ahead of the actual text of the book itself. I’ve never had to do all of this myself before, so it’s a challenge.
