“Weirdly ideological, but I couldn’t put it down,” I wrote on readernaut. “Actually one of his less insane novels, which is a good introduction. Still, he’s an entertaining, thought-provoking kind of crazy,” wrote Eric in response. A computer technician from the moon (an open penal colony, essentially) describes how a bunch of free-thinkers, with the help of a sentient computer, liberate their underground colony from the imperial grip of the economically oppressive Earthlings. Free thinkers as in its obvious who is Enlightened and who is not in this novel. Line marriages, p[ressure]-suits, Radical Jeffersonianism, artificial intelligence — the whole thing is like a strange Mary Jane where Heinlein just writes himself into all of his pet theories and wins the day. It was impossible to look away from for that very reason. Yet another surprise from my book club.
