The Moon Is a Harsh Mistress

A revolution on a lunar penal colony—aided by a self-aware supercomputer—provides the framework for a story of a diverse group of men and women grappling with the ever-changing definitions of humanity, technology, and free will. Widely acknowledged as one of Robert A. Heinlein's greatest works, it rose from the golden age of science fiction to become an undisputed classic—and a touchstone for the philosophy of personal responsibility and political freedom.
