It's his book boiled down to the basics. To really understand it you'll need to understand college freshman-level physics, but if you do, or you know anyone in that situation who is looking for a succinct but accurate introduction, this is what you should give them, in my opinion. Others will get good things out of it too.
Excellent recommendation. For other branches of geophysics, I would also point out Pierrehumbert's piece in Slate from a few years ago -- "The Myth of Saudi America"
