This sci-fi classic starts off interestingly enough: in an authoritarian society on the Moon, an engineer befriends a self-aware computer who has taken to practical joking. There are hundreds of different speculative fiction pathways this concept could have gone, instead Heinlein devoted the remaining ninety percent of the book detailing the administrative ins-and-outs of planning a revolution. Literally administrative minutia like how many members per sleeper cell and parliamentary rules. This makes for some severely dull reading. What an overrated piece of garbage.
