    A reflective statue is found at the bottom of one of Earth's oceans, having lain there for 1.5 billion years. Since humans have recently developed a time-slowing field and found that one such field cannot function within another, it is suspected that the "Sea Statue" is actually a space traveler within one of these time fields. Larry Greenberg, a telepath, agrees to participate in an experiment: a time-slowing field is generated around both Greenberg and the statue, shutting off the stasis field and revealing Kzanol.

    Phssthpok the Pak had been traveling for most of his thirty-two thousand years. His mission was to save, develop, and protect the group of Pak breeders sent out into space some two and a half million years before.

    Brennan was a Belter, the product of a fiercely independent, somewhat anarchic society living in, on, and around an outer asteroid belt. The Belters were rebels, one and all, and Brennan was a smuggler. The Belt worlds had been tracking the Pak ship for days, and Brennan figured to meet that ship first.

    Plateau, a colony in the Tau Ceti system, was settled by humans some 300 years before the plot begins. The colony world itself is a Venusian type planet with a dense, hot, poisonous atmosphere. It would be otherwise uninhabitable, except for a tall monolithic mesa that rises 40 miles up into a breathable layer in the upper atmosphere. This gives the planet a habitable area about half the size of California.

    Since fleeing the supernova chain reaction at the galactic core, the cowardly Puppeteers of the Fleet of Worlds have - just barely - survived one crisis after another: the rebellion of their human slaves, the relentless questing of the species of Known Space, the spectacular rise of the starfishlike Gw'oth, the onslaught of the genocidal Pak. Now fresh disaster looms, as though past crises have returned and converged. Who can possibly save the Fleet this time?

    Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

    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. Now, without warning, the Ringworld has vanished, leaving behind three rival war fleets. 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 they are cowards. But the crises converging upon the trillion puppeteers of the Fleet of Worlds go far beyond even the onrushing armadas.
