Pretty standard man / superman sci-fi novel. Frighteningly racist (tall, powerful, extra-white people are genetically superior to short, weak-minded, dark-skinned people) and primarily memorable as the first mention of lightsabers. No, not by name, but the High-born (yup actual name of uberrace) wield rods that when activated emit an energy beam from one end that are used like swords.
Despite the cover image on the Dell paperback (not shown as an option on Goodreads) with the woman in a skimpy cloud bikini, there is about zero point zero one percent sex in the book (High-born women wear diaphanous stuff, but from armpit to ankle, not the Princess Leia slave costume on the cover). There is a loyal love interest, but she's from the Wholesome Mom-in-waiting school, not the James Bond Girl school of '60s female stereotypes.
In the last 10-15 pages, the hero has to explain what happened, which is never a sign that the author did a good job in the first 150, but it's a zippy enough little story if you ignore the whole Aryan Brotherhood angle ...
It's barely worth two stars (one star if it was longer) ... I almost gave it a third because, having grown up on sci-fi written at about the same time, it feels like science fiction should. But when I sat down to write who I would recommend it to, I had to put down "teenage racists," which cost it the bonus point.
