"Adrenalizing, mind-stretching, conviction-testingunmatched by any contemporary!"--Theodore Sturgeon

In what is considered one of Heinlein's most hair-raising, thought-provoking, and outrageous adventures, the
master of modern science fiction tells the strange story of an even stranger world. It is twenty-first-century
Luna, a harsh penal colony where a revolt is plotted between a bashful computer and a ragtag collection of
maverick humans, a revolt that goes beautifully until the inevitable happens. But the problem with the inevitable
is that it always happens.

Winner of the 1967 Hugo award, this novel marked Heinlein's partial return to his best form. He draws many
historical parallels with the War of Independence, and clearly shows his own libertarian political views.
