Winner of both the Hugo and Nebula Awards for Best Novel, Ringworld remains a favorite among science fiction readers. Louis Wu, accompanied by a young woman with genes for luck, and a captured Kzin — a warlike species resembling 8-foot-tall cats — are taken on a space ship run by a brilliant 2-headed alien called Nessus. Their destination is the Ringworld, an artificially constructed ring with high walls that hold 3 million times the area of Earth. Its origins are shrouded in mystery. The adventures of Louis and his companions on the Ringworld are unforgettable…   “Larry Niven’s Ringworld remains one of the all-time classic travelogues of science fiction — a new and amazing world and fantastic companions.” - Greg Bear “If there isn’t a Ringworld out there somewhere, we ought to build one someday. Until then we have Larry Niven’s. A rich and fantastic story.”  - Fred Saberhagen “Our premier hard SF writer.”  - The Baltimore Sun “The scope of Larry Niven’s work is so vast that only a writer of supreme talent could disguise the fact as well as he can.”  - Tom Clancy “Niven is a true master.”  - Frederik Pohl Pierson's puppeteers, three-leg two-head aliens find immense structure in unexplored part of the universe. Frightened of meeting the builders, they send a team of two humans, a puppeteer and a kzin, eight-foot red-fur catlike alien. Ringworld is 180 million miles across, sun at center. But the expedition crashes, and crew face disastrously long trek.
