Military science fiction in which humans fight extinction in War of the Planet Burners, when remorseless aliens invade Earth in a near-future sci-fi novel. The Master Intelligence came to harvest what it needed from Earth. It sent its slave warriors to fight anyone who resisted. The aliens killed nearly all humans in an initial attack, and destroyed technology by eliminating electricity and nuclear weapons. That tactic had suppressed resistance on other planets. But humanity wouldn't give up.
