The Moon is a Harsh Mistress by Robert A. Heinlein

 

Great, surprising book. Mike the Computer alone is worth it, for Heinlein's witty fortelling of artificial intelligence. And the political discussion is bracing an intelligent, swirling around the Moon's struggle for independence from the Earth -- a lunar population  descended from convicts and conscripts banished from the mother planet -- the political discussion covers democracy, autocracy, libertarianism, and anarchy.
