Widely acknowledged as one of Robert A. Heinlein's greatest works, The Moon Is a Harsh Mistress 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. 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--themes that resonate just as strongly today as they did when the novel was first published.

The Moon Is a Harsh Mistress gives readers an extraordinary, thought-provoking glimpse into the mind of Robert A. Heinlein, who, even now, "shows us where the future is" (Tom Clancy).
