I don't know which post you're thinking of but I've read a lot of draw a box and it looks a super solid method to me. Not a book afaik but it's at least something to try!

Fundamentals are great to pursue on one's own, but The Natural Way To Draw has probably done more to help me than any other art book I can think of.

I guess it would depend on what kind of art a person wanted to get into. If they want to draw and paint realistic depictions of objects and people in the classical style, the Atelier books by Juliette Aristides might not be a bad foundation. I can't speak for all of them, but Classical Drawing Atelier is legit. https://www.aristidesarts.com/explore

If they wanna draw comics and things, I like Ben Caldwell's books. Action Cartooning and Fantasy Cartooning. Readily available new and used, I strongly endorse them.

If they want a guide for making fast, effective drawings that can communicate a concept or idea as well as form the foundation for a more elaborate piece of art later, Rapid Viz: A New Method for Visualization of Ideas by Kurt Hanks is excellent. It teaches a quick way of working to make good, useful sketches that can be used as is to get ideas across or built on to make finished art later.
