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
