Delmak-O is a dangerous planet. Though there are only 14 citizens, no one can trust anyone else and death can strike at any moment. The planet is vast and largely unexplored, populated mostly by gelatinous cube-shaped beings that give cryptic advice in the form of anagrams. Deities can be spoken to directly via a series of prayer amplifiers and transmitters, but they may not be happy about it. And the mysterious building in the distance draws all the colonists to it, but when they get there each sees a different motto on the front.

On an arid Mars, local bigwigs compete with Earth-bound interlopers to buy up land before the Un develops it and its value skyrockets. Martian Union leader Arnie Kott has an ace up his sleeve, though: an autistic boy named Manfred who seems to have the ability to see the future. In the hopes of gaining an advantage on a Martian real estate deal, powerful people force Manfred to send them into the future, where they can learn about development plans.

Ragle Gumm has a unique job: Every day he wins a newspaper contest. And when he isn’t consulting his charts and tables, he enjoys his life in a small town, in 1959. At least, that’s what he thinks. But then strange things start happening. He finds a phone book where all the numbers have been disconnected, and a magazine article about a famous starlet named Marilyn Monroe, whom he’s never heard of. Plus, everyday objects are beginning to disappear and are replaced by strips of paper with words written on them, like "bowl of flowers" and "soft-drink stand".

Hamilton Felix, the result of generations of genetic selection, finds his life as the ultimate man boring - until a gang of revolutionaries tries to enlist him in their cause.

Robert A. Heinlein wrote The Number of the Beast, which was published in 1980. In the book Zeb, Deety, Hilda, and Jake are ambushed by the alien "Black Hats" and barely escape with their lives on a specially configured vehicle (the Gay Deceiver) which can travel along various planes of existence, allowing them to visit parallel universes. However, unknown to most fans, Heinlein had already written a "parallel" novel about the four characters and parallel universes in 1977. 

One of Heinlein's best-loved works, The Rolling Stones follows the rollicking adventures of the Stone family as they tour the solar system. It doesn't seem likely for twins to have the same middle name. Even so, it's clear that Castor and Pollux Stone both have "Trouble" written in that spot on their birth certificates. Of course, anyone who's met their grandmother Hazel would know they came by it honestly.

Lummox has been the pet of the Stuart family for generations. With eight legs, a thick hide, and increasingly large size, Lummox is nobody's idea of man's best friend. Nevertheless, John Stuart XI, descendant of the starman who originally brought Lummox back to Earth, loves him. But when Lummox eats a neighbor's car and begins to grow again, the feds decide that enough is enough.

Jim Marlowe and his strange-looking Martian friend, Willis, are allowed to travel only so far. But one day Willis unwittingly tunes in to a treacherous plot that threatens all the colonists on Mars, and it sets Jim off on a terrifying adventure that could save - or destroy - them all.

Today the moon - tomorrow the stars. The Man Who Sold the Moon: A landmark volume in Heinlein’s magnificent Future History series. D. D. Harriman is a billionaire with a dream: the dream of Space for All Mankind. The method? Anything that works. Maybe, in fact, Harriman goes too far. But he will give us the stars....

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.

Don Harvey is a citizen of the Interplanetary Federation - yet no single planet can claim him as its own. His mother was born on Venus and his father on Earth, and Don himself was born on a spaceship in trajectory between planets. When his parents abruptly summon him away from school on Earth to join them on Mars, he has no idea he's about to be plunged into deadly interplanetary intrigue. But the ship Don is traveling on is unexpectedly diverted to Venus, where the colony has launched a revolution against Earth's control.

After the fall of the American Ayatollahs as foretold in Stranger in a Strange Land and chronicled in Revolt in 2100, the United States of America at last fulfills the promise inherent in its first Revolution: for the first time in human history there is a nation with Liberty and Justice for All. No one may seize or harm the person or property of another, or invade his privacy, or force him to do his bidding. Americans are fiercely proud of their re-won liberties and the blood it cost them; nothing could make them forswear those truths they hold self-evident. Nothing except the promise of immortality…

When a stranger attempting to deliver a cryptic message is shot dead at his dinner table, Richard Ames is thrown headfirst into danger, intrigue, and other dimensions where Lazarus Long still thrives, where Jubal Harshaw lives surrounded by beautiful women, and where a daring plot to rescue the sentient computer called Mike can change the direction of all human history.

A tale beloved by many fans of Robert A. Heinlein, Podkayne of Mars tells the story of a young Marswoman and her interplanetary adventures with her uncle and her genius brother. Told largely through Podkayne's diaries, the story details her travel to Earth with her two companions. Podkayne has definite plans on what to do and how to do it, but not everything is as it seems. She is suddenly thrust into the middle of life-or-death situations when the liner they are traveling on makes a stop at Venus.

The wickedest, most wonderful science fiction story ever created in our - or any - time. Anything can begin at a party in California - and everything does in this bold masterwork by a grand master of science fiction. When four supremely sensual and unspeakably cerebral humans - two male, two female - find themselves under attack from aliens who want their awesome quantum breakthrough, they take to the skies - and zoom into the cosmos on a rocket roller-coaster ride of adventure, danger, ecstasy, and peril.

Robert A. Heinlein has been hailed as one of the most forward-thinking science fiction writers of all time, and Expanded Universe (presented in two volumes) offers the perfect collection of his works to provide listeners with true insights into his uniquely creative mind.

When a beam of pink light begins giving a schizophrenic man named Horselover Fat (who just might also be known as Philip K.
