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.

The gigantic comet had slammed into Earth, forging earthquakes a thousand times too powerful to measure on the Richter scale, tidal waves thousands of feet high. Cities were turned into oceans; oceans turned into steam. It was the beginning of a new Ice Age and the end of civilization. But for the terrified men and women chance had saved, it was also the dawn of a new struggle for survival--a struggle more dangerous and challenging than any they had ever known....

The first interstellar ship, John Glenn, fled a solar system populated by rogue AIs and machine/human hybrids, threatened by too much nanotechnology, and rife with political dangers. The John Glenn’s crew intended to terraform the nearly pristine planet Ymir in hopes of creating a utopian society that will limit intelligent technology, but by some miscalculation they have landed in the wrong system.

Avalon was thriving. The cold sleep colonists from Earth had settled on a verdant, livable world. The fast and cunning predators humans named “grendels” were under control, and the mainland outposts well established. Avalon’s new mainland hydroelectric power station was nearly complete, and when on-line would compensate for the nuclear power systems lost in the Grendel Wars. Humans would have power, and with power came the ability to make all the necessities for life. They would survive. They would not survive as a spacefaring people.

The year is 2085, and humanity has spread throughout the solar system, a stable lunar colony is agitating for independence, and lunar tourism is on the rise.

Ali Kikaya will participate in the first live-action role playing game conducted on the Moon itself.

Doctor Toby Glyer has effected miracle cures with the use of nanotechnology. But Glyer’s controversial nanites are more than just the latest technological advance, they are a new form of life - and they have more uses than just medical.

Since fleeing the supernova chain reaction at the galactic core, the cowardly Puppeteers of the Fleet of Worlds have - just barely - survived one crisis after another: the rebellion of their human slaves, the relentless questing of the species of Known Space, the spectacular rise of the starfishlike Gw'oth, the onslaught of the genocidal Pak. Now fresh disaster looms, as though past crises have returned and converged. Who can possibly save the Fleet this time?

The newly liberated humans of the Fleet of Worlds and Sigmund Ausfaller, who had been transported by the Puppeteers from Earth to the Fleet, must contend not only with the sly Puppeteers but also the threat of the Pak, a very smart and utterly ruthless species who are fleeing the exploding galactic core in an armada of ships at near light speed. The Pak are headed towards the Fleet of Worlds, having destroyed entire planets in their wake.

A human expedition to colonize another star system is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure cupping a star, with a habitable area equivalent to many millions of Earths. And which, tantalizingly, is on a direct path heading toward the same system.

Science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape) continue the thrilling adventure of a human expedition to another star system that is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure cupping a star, with a habitable area equivalent to many millions of Earths.
