The most energetic future history ever written The Encyclopedia of Science Fiction
Pierson's puppeteers, strange, three-legged, two-headed aliens, have discovered an immense structure in a hitherto unexplored part of the universe. Frightened of meeting the builders of such a structure, the puppeteers set about assembling a team consisting of two humans, a puppeteer and a kzin, an alien not unlike an eight-foot-tall, red-furred cat, to explore it. The artefact is a vast circular ribbon of matter, some 180 million miles across, with a sun at its centre - the Ringworld. But the expedition goes disastrously wrong when the ship crashlands and its motley crew faces a trek across thousands of miles of the Ringworld's surface.
Larry Niven has won the prestigious Hugo Award five times. He is known to millions as the premier modern author of rigorous, scientifically consistent hard SF, the champion of 'SF without a net'.
