I've assembled all the pages from the original comic, collected all the extras I want to include, and drew the covers. Still have to write commentaries for the chapter breaks and the extras, draw the extra comic for book 3, and format the pages to the printer's specifications. All in all, I still have about a month's worth of work to do on the book at the most. And yeah, the preorder amount will probably determine if I decide to go through with these remaining tasks.
