SUMMARY: The war for human survival continues against the felinoid invaders from the planet Kzin

SUMMARY: In a new story, Larry Niven tells of the earliest days of the first Man-Kzin War. The surviving Kzin have been caged and are being studied. The monkey-boys have told them that their war is over. Incomprehensible to the Kzin, for whom no war is ever over. The humans are sure that the huge warcats cannot escape their prison--but they shouldn't make such bold assumptions.

SUMMARY: The Kzin were the mightiest warriors in the galaxy, which they were wasting no time in conquering, one star system at a time. Then those feline lords of creation ran into those ridiculous weed-eating pacifistic apes who called themselves humans. And the catlike Kzin found they had their collective tail caught in a meat grinder. When the mighty Kzin moved in to take over the monkey-infested worlds, they got clobbered. The humans, with their underhanded monkey cunning, turned communications equipment and space drives into weapons that cut the dauntless Kzin heroes into ribbons. And then those underhanded humans gained a faster-than-light drive, and no amount of screaming and leaping could keep the Kzin from losing their first war in centuries of successful conquest. But you can't keep a good warcat down, and the Kzin have by no means given up. New weapons, new strategies, and new leaders. Here they come again and those monkey-boys from Earth had better watch their backs. Once again, it's howling time in Known Space!

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.

The Perfect Crime... The invention of displacement booths produced one hell of a crime wave. If a man in; say, Hawaii could commit murder in, say, Chicago and be back in the time it would take him to visit the men’s room, he would have a perfect alibi. And the police would have a problem. But that’s only one of the problems found in Larry Niven’s universe. In this collection of stories all about teleportation, deep space, black holes, artificial worlds - Hole in Space, a (1974)[Collection]

Whether it’s God walking into the Draco Tavern, stony spirits talking to relatives, a robot plotting the ultimate murder, or the ability to see distinct patterns in the vibrations caused by uttering words and phrases … these stories will entertain you, make you laugh, make you think and, most importantly, make you question your own long-held views on life, the universe and everything else. The stories in this volume have been personally selected by Mike Resnick as his favorites among those that were published in Galaxy’s Edge magazine in 2013 and 2014. Authors include seasoned veterans such as Larry Niven and Mercedes Lackey, newcomers such as Andrea G. Stewart and Tina Gower, and writers from lands far and wide such as Sabina Theo from Bulgaria and Leena Likitalo from Finland. But all the stories have one thing in common: They are great stories … and like all great stories, need great readers.

In this sequel to “Ringworld” and “Ringworld Engineers,” the ring is still home to many alien species. The last Puppeteer is still manipulating those he can, and Louis Wu must meet even more new challenges and solve more technological problems in order for the hominid species to survive.

Loosely based on Larry Niven’s 1973 novella “Flash Crowd,” Red Tide continues to examine the social consequences of the impact of having instantaneous teleportation, where humans can instantly travel long distances in milliseconds. This is a theme that has fascinated the author throughout his career and even appears in his seminal work Ringworld, where the central character celebrates his birthday by instantly teleporting himself to different time zones, extending his “birthday.” The author also discussed the impact of such instantaneous transportation in his essay, “Exercise in Speculation: The Theory and Practice of Teleportation.” Larry Niven is joined by two younger writers, Brad R. Torgersen and Matthew J. Harrington, as they take on this challenging idea and further develop the theories and concepts that Niven originally presented in “Flash Crowd.”

Traces the earliest days of the first Man-Kzin War, during which humans foil the huge feline warriors' attempt to turn them into slaves by enslaving them instead, until one of the cats turns out to be gifted with mental telepathy.
