Book
Ringworld
by Larry Niven
Winner of the Hugo and Nebula Awards for best novel Four travelers come to the ringworld. . . Louis Wu: human and old; bored with having lived too fully for far too many years. Seeking a challenge, and all too capable of handling it. Nessus: a trembling coward, a puppeteer with a built-in survival pattern of nonviolence. Except that this particular puppeteer is insane. Teela Brown: human; a wide-eyed youngster with no allegiances, no experience, no abilities. And all the luck in the world. Speaker-To-Animals: kzin; large, orange-furred, and carnivorous. And one of the most savage life-forms known in the galaxy. Why did these disparate individuals come together? How could they possibly function together? And where, in the name of anything sane, were they headed?
Book
Ringworld Engineers
by Larry Niven
A return voyage to the astonishing world of Larry Niven’s Ringworld, with even more remarkable adventures and surprises, and a solution to that tantalizing question left from the earlier book: how was Ringworld built and by whom? It’s been twenty years since the quixotic and worldsweary Louis Wu discovered the Ringworld. Now he and Speaker-To-Animals are going back, captives of the Hindmost, a deposed puppeteer leader. With Louis’ help, the Hindmost intends to regain his status by bringing back such extraordinary treasures from the Ringworld that his fellow puppeteers will have to be impressed. But when they arrive, Louis discovers that the Ringworld is no longer stable . . . and will destroy itself within months. To survive he must locate the control center of the legendary engineers who built the planet. His quest becomes a wild and gripping venture, blended with the mysteries and spectacular technologies that only Larry Niven can conjure! Praise for Ringworld Engineers “For new readers, there’s fascinating adventure in plenitude. For old fans of Niven’s Known Space series, or of the original volume, there are all the fine, characteristic touches that delight us Niven fans, and which support his reputation for uncommon wittiness and fast narrative pace.”—Chicago Sun-Times “The Ringworld Engineers has all the imaginativeness, convincing detail, and narrative vivacity that have come to be associated with the works of Larry Niven. Furthermore, it answers a lot of questions that have been tantalizing his readers for a long time. Most highly recommended!”—Paul Anderson “When I finished The Ringworld Engineers, I cleared my calendar for a week, sat down, and reread every word of the Known Space cycle from scratch, then reread The Ringworld Engineers. It was worth the effort, and left me staggered by the breadth and scope of Larry’s vision. . . . If you count yourself as a true friend of Larry Niven, race right out and get this one.”—Analog Science Fiction Magazine “Another fine masterpiece from the master of science fiction . . . The coming conquest of space has always been a central myth of science fiction, and Larry Niven’s future worlds have made the most of it. The Ringworld itself is a dazzling notion, carrying the future evolution of technology about as far as possible.”—Jack Williamson “Adventurous exploration of a mind-boggling landscape.”—Publishers Weekly

Book
The Integral Trees
by Larry Niven
“Niven has come up with an idea about as far out as one can get. . . . This is certainly classic science fiction—the idea is truly the hero.”—Asimov’s Science Fiction Magazine When leaving Earth, the crew of the spaceship Discipline was prepared for a routine assignment. Dispatched by the all-powerful State on a mission of interstellar exploration and colonization, Discipline was aided (and secretly spied upon) by Sharls Davis Kendy, an emotionless computer intelligence programmed to monitor the loyalty and obedience of the crew. But what they weren’t prepared for was the smoke ring–an immense gaseous envelope that had formed around a neutron star directly in their path. The Smoke Ring was home to a variety of plant and animal life-forms evolved to thrive in conditions of continual free-fall. When Discipline encountered it, something went wrong. The crew abandoned ship and fled to the unlikely space oasis. Five hundred years later, the descendants of the Discipline crew living on the Smoke Ring no longer remember their origins. Earth is more myth than memory, and no recollection of the State remains. But Kendy remembers. And just outside the Smoke Ring, Discipline waits patiently to make contact with its wayward children.

A Fire Upon The Deep
by Vernor Vinge
A Fire Upon the Deep is the big, breakout book that fulfills the promise of Vinge's career to date: a gripping tale of galactic war told on a cosmic scale. Thousands of years hence, many races inhabit a universe where a mind's potential is determined by its location in space, from superintelligent entities in the Transcend, to the limited minds of the Unthinking Depths, where only simple creatures and technology can function. Nobody knows what strange force partitioned space into these "regions of thought," but when the warring Straumli realm use an ancient Transcendent artifact as a weapon, they unwittingly unleash an awesome power that destroys thousands of worlds and enslaves all natural and artificial intelligence. Fleeing the threat, a family of scientists, including two children, are taken captive by the Tines, an alien race with a harsh medieval culture, and used as pawns in a ruthless power struggle. A rescue mission, not entirely composed of humans, must rescue the children-and a secret that may save the rest of interstellar civilization. A Fire Upon The Deep is the winner of the 1993 Hugo Award for Best Novel.

A Deepness in the Sky
by Vernor Vinge
After thousands of years searching, humans stand on the verge of first contact with an alien race. Two human groups: the Qeng Ho, a culture of free traders, and the Emergents, a ruthless society based on the technological enslavement of minds. The group that opens trade with the aliens will reap unimaginable riches. But first, both groups must wait at the aliens' very doorstep for their strange star to relight and for their planet to reawaken, as it does every two hundred and fifty years.... Then, following terrible treachery, the Qeng Ho must fight for their freedom and for the lives of the unsuspecting innocents on the planet below, while the aliens themselves play a role unsuspected by the Qeng Ho and Emergents alike. More than just a great science fiction adventure, A Deepness in the Sky is a universal drama of courage, self-discovery, and the redemptive power of love. A Deepness in the Sky is a 1999 Nebula Award Nominee for Best Novel and the winner of the 2000 Hugo Award for Best Novel.
