The graphic novel that got cover blurbs by four people with something like seven Hugo nominations between them.

It took about four years. There is one spread near the end that took about six months; you will know it when you see it.

It is utterly impossible to get anyone to read now, as it is entirely designed around horizontally scrolling a screen the size of the tablet, and every single site/app trying to consolidate all comics readers into their own corporate silo is focused on vertically scrolling a phone screen, and there is no way in hell I am going to reformat all this very landscape-oriented multi-track stuff for that.
