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.
"The Uplift books are as compulsive reading as anything ever published in the genre."
