Rainbow Mars

Five-time Hugo Award winner Larry Niven weaves together time travel and fantasy to create an utterly unique novel on the origin of Martian "canals." Thought provoking, vivid, viciously smart and wildly funny, "Rainbow Mars" is sci-fi at its best.Hanville Svetz was born into a future to match the sorriest prediction of Greenpeace. Most life forms are extinct. It is Svetz's job to go back in time and retrieve them, or at least it was until his Institute for Tempoarl Research was transferred. Now, with a new boss obsessed with stars and planets, Svetz must figure out why the Martian canals have gone dry, and what it means for Earth's future. And yes Mars was inhabited! When Svetz learns how their sapient species were wiped out, he realizes that Earth could soon fall victim to a similar fate. Together with his dog Wrona, a visitor from the distant past, and Milya, an astronaut with her own complex history, Svetz must struggle to unravel a puzzle that will tax not just his rational mind, but the very limits of his imagination.
