Search Worlds Without End

This work takes its readers on a thrilling journey to the planets and moons of our solar system, including Mars and Saturn before heading, at several times the speed of light, to Alpa Centauri, where they explore an Eden-like planet.

Fleet of Worlds marks Larry Niven's first full novel-length collaboration within his Known Space universe, the playground he created for his bestselling Ringworld series. Teaming up with fellow SF writer Edward M. Lerner, Fleet of Worlds takes a closer look at the Human-Puppeteer (Citizens) relations and the events leading up to Niven's first Ringworld novel.

Kirsten Quinn-Kovacs is among the best and brightest of her people. She gratefully serves the gentle race that rescued her ancestors from a dying starship, gave them a world, and nurtures them still. If only the Citizens knew where Kirsten's people came from....

A chain reaction of supernovae at the galaxy's core has unleashed a wave of lethal radiation that will sterilize the galaxy. The Citizens flee, taking their planets, the Fleet of Worlds, with them.

Someone must scout ahead, and Kirsten and her crew eagerly volunteer. Under the guiding eye of Nessus, their Citizen mentor, they explore for any possible dangers in the Fleet's path--and uncover long-hidden truths that will shake the foundations of worlds.

For too long, the Puppeteers have controlled the fate of worlds. Now Sigmund is pulling the strings...

Covert agent Sigmund Ausfaller is Earth's secret weapon, humanity's best defense against all conspiracies, real and potential - and imaginary - of foes both human and alien. Who better than a brilliant paranoid to expose the devious plots of others?

He may finally have met his match in Nessus, representative of the secretive Puppeteers, the elder race who wield vastly superior technologies. Nessus schemes in the shadows with Earth's traitors and adversaries, even after the race he represents abruptly vanishes from Known Space.

As a paranoid, Sigmund had always known things would end horribly for him. Only the when, where, how, why, and by whom of it all had eluded him. That fog has begun to lift...

But even Sigmund has never imagined how far his investigations will take him - or that his destiny is entwined with the fates of worlds.

Worlds closer to the galatic core than Known Space are --or were-- home to intelligent speciers. Some learned of the core explosion in time to flee. Destroyer of Worlds opens in 2670, ten years after Juggler of Worlds closes; with refugee species fleeing in an armada of ramscoops in the direction of the Fleet of Worlds. The onrushing aliens are recognized as a threat; they have left in their trail a host of desolated worlds: some raided for supplies, some attacked to eliminate competition, and some for pure xenophobia.

Only the Puppeteers might have the resources to confront this threat--but the Puppeteers are philosophical cowards... they don't confront anyone. They need sepoys to investigate the situation and take action for them. The source of the sepoys? Their newly independent former slave world, New Terra.

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.

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 Worlds' 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 Worlds' 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.

Aleister Lanoe has won a stunning victory against the alien armada that threatened Niraya, but it's not enough to satisfy his desire for vengeance. He won't rest until he's located the armada's homeworld and reduced it to ashes.

Yet his personal vendetta will have to wait. Lanoe now faces a desperate race against time, and the merciless Centrocor corporation, if he's to secure the Earth's future--and discover the truth he seeks.

The battle is over. But the war has only just begun.

The war that destroyed everything lasted a single day. After an initial nuclear strike, the Earth's population was further devastated by an insidious bioweapon targeting anyone above the age of puberty. Now most of what's left of human civilization gathers on New New York, one of the few orbiting Worlds that remain.

Monitoring the Earth below from the floating habitat, Marianne O'Hara searches for signs of life - and, in particular, for Jeff Hawking, her former lover, who survived the viral nightmare thanks to a biological anomaly that rendered him immune. But Jeff is not the sole surviving adult in this landscape of death, ruin, and feral children, and those who fled to safety underground are being seduced by a terrible new religion preaching blood and vengeance. The last war, it seems, is not over - and the last hope for preventing the final holocaust may be Marianne O'Hara.

The Earth is no more, an uninhabitable shell following the one-day war that obliterated the population. In the decades that followed, the surviving Worlds orbiting the dead planet have become the last refuge of humankind. With the discovery of a possibly habitable planet in a distant star system, ten thousand brave colonists are preparing to depart from New New York aboard the interstellar vessel Newhome. Among them is Marianne O'Hara, who will ultimately control the fate of what remains of the human race.

The momentous voyage is plagued from the start by ignorance and sabotage, and by the dark tenets of a nihilistic religion dedicated to ultimate destruction. But despite the many trials and tragedies, the spacefarers - and particularly Marianne and her loved ones - will be forced to endure. There is no turning back once the journey begins... for soon there will be nowhere left to return to.
