Miki Falls, an American manga!

So the other day I was watching Mark Crilley's YouTube channel (click here to check it out), and people were talking about how they ordered his manga drawing book on Amazon.com. Then some people were saying how they got his 4 book series Miki Falls. I rented it from the library but I haven't read it yet. I'll probably get to it sometime in the near future though. I've mainly been watching anime.
