Infinity's Shore Hardcover - 1996

From the publisher

Nebula and Hugo award-winning author David Brin continues his bestselling Uplift series in this second novel of a bold new trilogy. Imaginative, inventive, and filled with Brin's trademark mix of adventure, passion, and wit, "Infinity's Shore" carries us further than ever before into the heart of the most beloved and extraordinary science fiction sagas ever written.
For the fugitive settlers of Jijo, it is truly the beginning of the end. As starships fill the skies, the threat of genocide hangs over the planet that once peacefully sheltered six bands of sapient beings. Now the human settlers of Jijo and their alien neighbors must make heroic--and terrifying--choices. A scientist must rally believers for a cause he never shared. And four youngsters find that what started as a simple adventure--imitating exploits in Earthling books by Verne and Twain--leads them to the dark abyss of mystery. Meanwhile, the "Streaker," with her fugitive dolphin crew, arrives at last on Jijo in a desperate search for refuge. Yet what the crew finds instead is a secret hidden since the galaxies first spawned intelligence--a secret that could mean salvation for the planet and its inhabitants...or their ultimate annihilation.
