David Brin's Uplift novels are among the most thrilling and extraordinary science fiction ever written. Sundiver, Startide Rising, and The Uplift War—a New York Times bestseller—together make up one of the most beloved sagas of all time. Brin's tales are set in a future universe in which no species can reach sentience without being "uplifted" by a patron race. But the greatest mystery of all remains unsolved: who uplifted humankind?

The Terran exploration vessel Streaker has crashed in the uncharted water world of Kithrup, bearing one of the most important discoveries in galactic history. Below, a handful of her human and dolphin crew battles armed rebellion and a hostile planet to safeguard her secret—the fate of the Progenitors, the fabled First Race who seeded wisdom throughout the stars.

Gordon Krantz survived the Doomwar only to spend years crossing a post-apocalypse United States looking for something or someone he could believe in again. Ironically, when he's inadvertently forced to assume the made-up role of a "Restored United States" postal inspector, he becomes the very thing he's been seeking: a symbol of hope and rebirth for a desperate nation. Gordon goes through the motions of establishing a new postal route in the Pacific Northwest, uniting secluded towns and enclaves that are starved for communication with the rest of the world. And even though inside he feels like a fraud, eventually he will have to stand up for the new society he's helping to build or see it destroyed by fanatic survivalists. This classic reprint is not one of David Brin's best books, but the moving story he presents overcomes mediocre writing and contrived plots.
