Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but which looks completely different. Particularly as it’s carried though space on the back of a giant turtle (sex unknown). It plays by different rules. But then, some things are the same everywhere. The Disc’s very existence is about to be threatened by a strange new blight: the world’s first tourist, upon whose survival rests the peace and prosperity of the land.

They first appear as a series of dots on astronomical plates, heading from Saturn directly toward Earth. Since the ringed planet carries no life, scientists deduce the mysterious ship to be a visitor from another star. The world's frantic efforts to signal the aliens go unanswered. The first contact is hostile: the invaders blast a Soviet space station, seize the survivors, and then destroy every dam and installation on Earth with a hail of asteriods.

For a game, the gods have given the world 12 Swords of Power so that they might be amused as the nations battle for their possession. But Vulcan the Smith has had his own little joke: the Swords can kill the gods themselves. What started out as Divine Jest has become all too serious as the gods fight to recover the Swords, and mortals discover that the mantle of power is more delicious and more terrible than anything they could have imagined.

What happens to the would-be peacemakers when they find themselves in the middle of something else? Something dangerous, something highly advanced...and something familiar? If humanity is wise, we will prepare for everything we can imagine. But we cannot prepare for what we cannot imagine. It might be benign, it might be malign, or it might be a sign. You just have to know where to look.

Jordan McKell has a problem with authority. Unfortunately for him, the iron-fisted authority of the powerful Patthaaunutth controls virtually every aspect of galactic shipping. In order to survive, Jordan ekes out a living dabbling in interstellar smuggling for outlaw concerns that represent the last vestiges of free trade in the galaxy. So when Jordan and his partner, Ixil - an alien with two ferret-like "outhunters" linked to his neural system - are hired by a mysterious gentleman to fly a ship and its special cargo to Earth, they jump at the job.

The year is 2650. Seventy-five years ago, an alien fleet attacked Earth. Without warning. Without mercy. We were not prepared. Hundreds of millions perished. Dozens of cities burned. We nearly lost everything. Then the aliens abruptly left. We rebuilt. We armed ourselves. We swore: never again. But the aliens never came back. Until now. With overwhelming force the aliens have returned, striking deep into our territory, sending Earth into a panic.

The United States government is given a warning by the preeminent biophysicists in the country: current sterilization procedures applied to returning space probes may be inadequate to guarantee uncontaminated re-entry to the atmosphere.
