Robert A. Heinlein is widely and justly regarded as the greatest practitioner of the art of science fiction who has ever lived. Here are two of his greatest short novels: Gulf, in which the greatest super-spy of them all is revealed as the leader of a league of supermen and women who can’t quite decide what to do with the rest of us. And Lost Legacy, in which it is proved that we are all members of that league - or would be, if we but had eyes to see.

One of Heinlein's best-loved works, The Rolling Stones follows the rollicking adventures of the Stone family as they tour the solar system.

Of course, anyone who's met their grandmother Hazel would know they came by it honestly.

. C. “Scar” Gordon was on the French Riviera recovering from a tour of combat in Southeast Asia, but he hadn’t given up his habit of scanning the personals in the newspaper.

The totalitarian East has triumphed in a massive invasion, and the United States has fallen to a dictatorial superpower bent on total domination. That power is consolidating its grip through concentration camps, police state tactics, and a total monopoly upon the very thoughts of the conquered populace. A tiny enclave of scientists and soldiers survives, unbeknownst to America’s new rulers. It’s six against six million - but those six happen to include a scientific genius, a master of subterfuge and disguise who learned his trade as a lawyer-turned-hobo, and a tough-minded commander....
