Sowell on Economics?

A question: Are Thomas Sowell's books worth reading? I'm particularly interested in his books on economics, namely Basic Economics, Applied Economics, and Economic Facts and Fallacies. I don't need these books to be philosophically perfect, but I'd like them to be good and clear on the economics.

I'm skeptical because I read his book Marxism: Philosophy and Economics some years ago. Although I read it carefully, I learned absolutely nothing from it. It was just a long string of floating abstractions that illuminated nothing. So I'm reluctant to try again, but I'd like to read some economics -- or rather listen, and he seems to be the only potentially decent author available on Audible.

So what say you?
