Search Worlds Without End

In this first collaboration by science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape), the limits of wonder are redrawn once again as a human expedition to another star system is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure half-englobing a star, with a habitable area equivalent to many millions of Earths...and it's on a direct path heading for the same system as the human ship.

A landing party is sent to investigate the Bowl, but when the explorers are separated--one group captured by the gigantic structure's alien inhabitants, the other pursued across its strange and dangerous landscape--the mystery of the Bowl's origins and purpose propel the human voyagers toward discoveries that will transform their understanding of their place in the universe.

Science fiction masters Larry Niven (Ringworld) and Gregory Benford (Timescape) continue the thrilling adventure of a human expedition to another star system that is jeopardized by an encounter with an astonishingly immense artifact in interstellar space: a bowl-shaped structure cupping a star, with a habitable area equivalent to many millions of Earths. And which, tantalizingly, is on a direct path heading toward the same system the human ship is to colonize.

Investigating the Bowl, or Shipstar, the human explorers are separated--one group captured by the gigantic structure's alien inhabitants, the other pursued across its strange and dangerous landscape--while the mystery of the Shipstar's origins and purpose propel the human voyagers toward discoveries that transform their understanding of their place in the universe.

Audacious astronauts encounter bizarre, sometimes deadly life forms, and strange, exotic, cosmic phenomena, including miniature black holes, dense fields of interstellar plasma, powerful gravity-emitters, and spectacularly massive space-based, alien-built labyrinths. Tasked with exploring this brave, new, highly dangerous world, they must also deal with their own personal triumphs and conflicts.
