When the Sunseeker laves Earth, bound for the planet called "Glory", its crew knows they will never see home again. None of them can ever have imagined, however, what they will find along the way. A gargantuan object, with its own star nettled inside. The bowl shaped structure is following the same path as the Sunseeker and it has a habitable are the size of millions of Earths, A landing party is sent to the surface, where they encounter some of the structures inhabitants - wildly differing species, and not all of them friendly.

Pierson's puppeteers, strange, three-legged, two-headed aliens, have discovered an immense structure in a hitherto unexplored part of the universe. Frightened of meeting the builders of such a structure, the puppeteers set about assembling a team consisting of two humans, a puppeteer and a kzin, an alien not unlike an eight-foot-tall, red-furred cat, to explore it. The artefact is a vast circular ribbon of matter, some 180 million miles across, with a sun at its centre - the Ringworld. But the expedition goes disastrously wrong when the ship crashlands and its motley crew faces a trek across thousands of miles of the Ringworld's surface.

Writing separately, Larry Niven and Jerry Pournelle are responsible for a number of science fiction classics, such as the Hugo and Nebula Award-winning Ringworld, Debt of Honor, and The Integral Trees. Together they have written the critically acclaimed bestsellers Inferno, Footfall, and The Legacy of Heorot, among others.

The Mote In God's Eye is their acknowledged masterpiece, an epic novel of mankind's first encounter with alien life that transcends the genre.

A new place is being built, a world of huge dimensions, encompassing millions of miles, stronger than any planet before it. There is gravity, and with high walls and its proximity to the sun, a livable new planet that is three million times the area of the Earth can be formed. We can start again!

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 hydroe

For decades, the spacefaring species of Known Space have battled over the largest artifact--and grandest prize--in the galaxy: the all-but-limitless resources and technology of the Ringworld. But without warning the Ringworld has vanished, leaving behind three rival war fleets.
"Something" must justify the blood and treasure that have been spent. If the fallen civilization of the Ringworld can no longer be despoiled of its secrets, the Puppeteers will be forced to surrender theirs. Everyone knows that the Puppeteers are cowards.
But the crises converging upon the trillion Puppeteers of the Fleet of Worlds go far beyond even the onrushing armadas:
Adventurer Louis Wu and the exiled Puppeteer known only as Hindmost, marooned together for more than a decade, escaped from the Ringworld before it disappeared. And throughout those years, as he studied Ringworld technology, Hindmost has plotted to reclaim his power ...
Ol't'ro, the Gw'oth ensemble mind--and the Fleet of World's unsuspected puppet master for a century--is deviously brilliant. And, increasingly unbalanced ...
Proteus, the artificial intelligence on which--in desperation--the Puppeteers rely to manage their defenses, is outgrowing its programming. And the supposed constraints on its initiative ...
Sigmund Ausfaller, paranoid and disgraced hero of the lost human colony of New Terra, knows that "something" threatens his adopted home world. And that it must be stopped ...
Achilles, the megalomaniac Puppeteer, twice banished--and twice rehabilitated--sees the Fleet of World's existential crisis as a new opportunity to reclaim supreme power. Whatever the risks ...
One way or another, the fabled race of Puppeteers may have come to the end of their days in "Fate of Worlds, "the final installment to Larry Niven and Edward M. Lerner's "Fleet of Worlds "series.

Robert Heinlein called it "possibly the finest science fiction novel I have ever read." "The San Francisco Chronicle" declared that "as science fiction, "The Mote in God's Eye" is one of the most important novels ever published." Now Larry Niven and Jerry Pournelle, award winning authors of such bestsellers as "Footfall "and "The Legacy of Heorot, " return us to the Mote, and to the universe of Kevin Renner and Horace Bury, of Rod Blaine and Sally Fowler. There, 25 years have passed since humanity quarantined the mysterious aliens known as Moties within the confines of their own solar system. They have spent a quarter century analyzing and agonizing over the deadly threat posed by the only aliens mankind has ever encountered-- a race divided into distinct biological forms, each serving a different function. Master, Mediator, Engineer. Warrior. Each supremely adapted to its task, yet doomed by millions of years of evolution to an inescapable fate. For the Moties must breed-- or die. And now the fragile wall separating them and the galaxy beyond is beginning to crumble.

Some twenty years have passed since the passengers and crew of the starship Geographic established a colony on the hostile alien world of Avalon. In that time, a new generation has grown up in the peace and serenity of the island paradise of Camelot, igno

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....@lt;br@gt;"Massively entertaining."@lt;br@gt;CLEVELAND PLAIN-DEALER
