Ringworld's Children

Fleeing the supernova chain reaction at the galactic core, the cowardly Puppeteers of the Fleet of Worlds have---just barely---survived. They’ve stumbled from one crisis to the next: The rebellion of their human slaves. The relentless questing of the species of Known Space. The spectacular rise of the starfish-like Gw’oth. The onslaught of the genocidal Pak. 

Catastrophe looms again as past crises return---and converge. Who can possibly save the Fleet of Worlds from its greatest peril yet?

Louis Wu? Trapped in the Wunderland civil war, all he wants is to go home---but the only possible escape will plunge him into unknowable danger. 

Ol’t’ro? The Gw’oth ensemble mind fled across the stars to establish a colony world free from tyranny. But some problems cannot be left behind, and other problems---like the Fleet of Worlds itself---are racing straight at them. 

Achilles? Despite past disgrace, the charismatic Puppeteer politician knows he is destined for greatness. He will do anything to seize power---and to take his revenge on everyone who ever stood in his way.

Nessus? The insane Puppeteer scout is out of ideas, out of resources, with only desperation left to guide him.  

Their hopes and fears, dreams and ambitions are about to collide. And the winner takes . . . worlds.

In this first collaboration by science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape), the limits of wonder are redrawn once again as a human expedition to another star system is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure half-englobing a star, with a habitable area equivalent to many millions of Earths…and it’s on a direct path heading for the same system as the human ship.

A landing party is sent to investigate the Bowl, but when the explorers are separated—one group captured by the gigantic structure’s alien inhabitants, the other pursued across its strange and dangerous landscape—the mystery of the Bowl’s origins and purpose propel the human voyagers toward discoveries that will transform their understanding of their place in the universe.
