Just want to note that the novel noted in the first post, The Moon Is A Harsh Mistress, is a great read. I think I read it after seeing it recommended in Mary Robinette Kowal's Lady Astronaut series, but it's a nice balance of technical and science fiction with politics, almost like a condensed version of KSR's Mars Trilogy. It's mostly (not entirely) devoid of the more typical Heinlein sexism/objectification.
