For clarity: the Mayan calendar has nothing to do with the book besides me having a fun target date for publication.
Importantly, the final version sets the illustration plan for the entire series. I looked to 7 young artists each to do one illustration for the book. As the series progresses and the heroes age, artist ages will go up as well. Though with each book, I'll look for a NEW set of 7 artists. So the goal is to have 49 illustrations by 49 artists after 7 books are finished.
I will soon have a site up specifically for this series of books as well, so kids can come and ask questions and read about its development. Also so they can see about contributing art for future books when we're ready for that stage.
