This was posted in a facebook group I belong too. Looks like it could be a good book. It's a Kickstarter product which basically means limited run so long as they get enough people to sign up for it.
I've gotten several books this way and have no complaints other than the wait time is horrendous. They are not printed until all the goals are met
