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.

Mike and Annie, refugees from the world outside, find a home underground, behind the scenes of Dreamworld, a theme park where hope exists as it does nowhere else. But Dreamworld is threatened by a jealous competitor who kills what he can’t have. As if this were not trouble enough, the two discover that each day there are more of the “trolls” who maintain Dreamworld than there were the day before. As the trolls continue to multiply, they must discover why, or it could mean the end of Dreamworld - and the real world.

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.

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.

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.

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 21st-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 that's the problem with the inevitable: it always happens.

Meet Roger. Skilled with words, languages come easily to him. He instinctively understands how the world works through the power of story. Meet Dodger, his twin. Numbers are her world, her obsession, her everything. All she understands, she does so through the power of math. Roger and Dodger aren’t exactly human, though they don’t realize it. They aren’t exactly gods, either. Not entirely. Not yet. Meet Reed, skilled in the alchemical arts like his progenitor before him. Reed created Dodger and her brother. He’s not their father. Not quite. But he has a plan.

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…
