Query: so very well crafted

The ERB Mars series are very good, perhaps even better than the Tarzan books. There is an evil genius in this, a damsel who needs rescuing, and lots of adventure for our hero. What a pity Hollywood doesn't make movies of books like this. I read these in high school, and I still read them now, from time to time. If they had stuff like this in high school, instead of dreary English novels from the 1800's, they'd have boys who actually read the text, instead of going nuts.A Fighting Man of Marsis also very good.
