This book has been staring at me for years and I have never opened it up but I’m going to take it back to Austin with me and finally read it. I love A. E. Van Vogt, prolly one of the craziest sf authors ever. His later work blows cuz he became a Scientologist. But this book was originally serialized in a magazine in 1950 so it should be good. I’d say don’t read anything after 1970 but that may be too late. Here’s the back cover blurb: “12,000 A.D. – The Earth, after the atomic holocaust, had reverted to a strange kind of barbarism where men could build spaceshipts but could not communicate except by the most primitive means. Alien invaders had been sighted at the edge of the galaxy – but no one took action. Only one man, THE WIZARD OF LINN could save the decadent empire and with his mysterious powers, prevent the Earth’s destruction.” Wow. Such bad grammar.
