In 1967, four years after the Cuban Missile brought the very real possibility of a planet-wide nuclear annihilation into mainstream American consciousness John Brunner's Day Of The Star Cities (aka Age Of Miracles) was released.
Without warning, all the atomic weapons and fissionable material on Earth explode. Panic, death and chaos reigned for months before life on Earth reverted back to the Stone Age. By that time, scattered reports were already coming in of five mysterious star-shaped cities scattered over the globe - huge areas of flickering light and awesome free energy, disorienting to human senses and completely impregnable to attack. These aliens had ignited all nuclear and atomic weapons then built their bases on Earth. But were they conquering Earth or up to something else?
The book takes man and reduces him to an animal state using by his own weaponry. If that wasn't awful enough the book then sets up the truly alien, crystalline based multidimensional beings as the dominant form of life.
Brunner forces his survivors to attempt to communicate with their new masters. Doing so, his ragged, radioactive survivors confront sense inversion - receiving sensory information that is not analogous to the basic five human senses including magnetoception and electroception.
