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.

In what is considered one of his most hair-raising, thought-provoking, and outrageous adventures, the master of modern Sci-Fi tells the strange story of an even stranger world-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.

Robert Anson Heinlein (1907-1988) was born in Missouri. He served five years in the U.S. Navy, then studied mathematics and physics at the graduate school of UCLA, took a variety of jobs, and owned a silver mine before beginning to write science fiction in 1939. His novels have won the Hugo Award, and in 1975 he received the First Grand Master Nebula Award for lifetime achievement.
