The Singers of Time Author:Frederik Pohl, Jack Williamson Based on Stephen Hawking's theories the authors take us to a future where humanity has sold its birthright - and is happy in the bargain. — Earth has changed after the arrival of a superior alien race, dubbed the "Turtles" by humans. They have conquered Earth without a fight. They are bringers of peace, prosperity, improved medicine... more », science, and beneficial trade.
The catch was they did not allow petty political squabbles and the first things they bought were Earth's outdated military establishments and space bases. They objected strongly to humans who pursued 'non-turtle' science and cosmology, which were blasphemous to ther own beliefs. Most people did not object to being treated like wayward children.
Things change quickly when The Mother, the single female of the Turtle species, disapears. With no hope of continuing their race alone, the Turtles need HUMAN help and draft a space pilot named Krake, the only human to ever fly a Turtle waveship, to convey their search party on a mysterious journey.
Along with a pair of male twins, their shared love, Dr. Sue-Ling Kwan, a farm girl named Moon and the half sentient beast she loves, Krake takes off on a hazardous journey that would take all of them through the greatest secrets of the universe.« less
