The Moon is a Harsh Mistress by Robert Heinlein

This book seriously addresses questions of politics and free will under the guise of science fiction. While there's a lot of technical information about the communications systems and ballistics used by Mycroft (the artificial intelligence that coordinates the revolution), the book takes on the question of political self-determination. Written in a dialect supposed to have developed on the moon, the prose isn't the most elegant I've ever read. For me, the most compelling relationship in the book (and the most compelling reason to read the book) was the friendship between Mannie and Mike. I'm grateful to the friend who lent me his copy.
