The Moon is a Harsh Mistress by Robert A. Heinlein
Widely regarded as one of the most prominent writers of science fiction in the 20th century, it's always been an oversight that I hadn't read Heinlein. Of his works I had been told that variously that this is the best and most accessible.
It depicts a future uprising on the moon against its colonial earth-based authorities. Our main characters, with the aid of a sentient computer (the most interesting personality in the book) begin a conspiracy to overthrow these authorities and establish their own state.
I didn't agree with the politics, which are a little idiosyncratic, based mostly on libertarian capitalism but which also seem to legitimise such things as rigging elections, terrorism, summary execution and so forth.
That said, the prose is quirky and interesting, and the unfolding revolution is quite thrilling to observe. Heinlein's quality is such that one finds oneself rooting for the participants despite the above, and also despite a couple of plot contrivances that are used along the way.
