At his death in 1988, Robert A. Heinlein left a legacy that almost single-handedly defined modern science fiction. But one of Heinlein's masterpieces was never finished. In 1955, he began work on Variable Star, a powerful and passionate tale of two young lovers driven apart by pride, power, and the vastness of interstellar time and space. Now, the Heinlein estate has authorized award-winning author Spider Robinson to expand his outline into a full-length novel. And the result is vintage Heinlein.

Dr. Tyson Klein is a quantum physicist who has dedicated his entire life to his research. At CERN, he analyses data generated by the Large Hadron Collider, the world's biggest and most powerful particle accelerator. Now, Ty believes he's found a pattern in its output. It looks like an organised data stream, being broadcast over what he calls a quantum radio. Could it be a signal from another universe? A message sent from the future? Or something else entirely?

In The Menace from Earth, Robert A. Heinlein, a master of science fiction, presents startling stories of time and space. On the day past tomorrow, time has ended and man has begun his endless journey out into the universe. For those on the Pluto colony, Earth Satellite Base holds the only possible reprieve from a terrifying death sentence. Meanwhile on Earth, alien intelligence prowls the skies, kidnapping people for its own inhuman amusement.

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.

Ross Jenkins, Art Mueller, and Morris Abrams are not your average high-school students. While other kids are cruising around in their cars or playing ball, this trio, known as the Galileo Club, is experimenting with rocket fuels. Art's uncle, the nuclear physicist Dr. Donald Cargraves, offers them the opportunity of a lifetime: to construct and crew a rocket that will take them to the moon. But there are those who don't share their dream and who will stop at nothing to keep their rocket grounded.

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.

North Power Air is in trouble. Their aircraft are crashing at an alarming rate and no one can figure out the cause. Desperate for an answer, they turn to Waldo, a crippled misanthropic genius who lives in a home in orbit around Earth, where the absence of gravity means that his feeble muscle strength does not confine him helplessly in a wheelchair. But Waldo has little reason to want to help the rest of humanity - until he learns that the solution to Earth’s problems also holds the key to his own.

After firewalking in Polynesia, fundamentalist Minister Alexander Hergensheimer never saw the world the same. Now called Alec Graham, he was in the middle of an affair with his stewardess, Margrethe, and natural disasters kept following them. First, there was an impossible iceberg that wrecked the ship in the tropics; then, after being rescued by a Royal Mexican plane, they were hit by a double earthquake. To Alex, the signs were clear that Armageddon and the Day of Judgment were near.

. 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. One ad in particular leapt out at him: "Are you a coward? This is not for you. We badly need a brave man. He must be 23 to 25 years old, in perfect health, at least six feet tall, weigh about 190 pounds, fluent English with some French, proficient with all weapons, some knowledge of engineering and mathematics essential...."

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

A divorced substitute teacher living with his cat in a house his siblings want to sell, all he wants is to open a pub downtown, if only the bank will approve his loan. Then his long-lost uncle Jake dies and leaves his supervillain business (complete with island volcano lair) to Charlie. But becoming a supervillain isn't all giant laser death rays and lava pits.

But Mark isn't ready to give up yet.
