It's such an odd coincidence to see this now; I just discovered this series a week ago. I teach elementary school science and math, and I've already used a few excerpts from this (from Universe and Calculus) to help illustrate important ideas. I'm also a huge fan of Gonick's The Cartoon Guide to Genetics, which I'm using with the younger kids. As far as I'm concerned, we'd replace pretty much every textbook with comic books.
If you are a complete newbie, I'd recommend "Cartoon Guide To Genetics". Sadly, it is over a decade old at this point. If anyone has a more contemporary reading list, I would also be interested.
