Their culture is entering a period of explosive growth that could end in tragedy, due in part to a dangerous nuclear arms race and in part to the Emergents' desire to enslave them.

The Spiders have just come out of a two-century-long suspended animation made necessary by the fluctuations of their erratic sun. Unfortunately, the Qeng Ho must compete with another, less beneficent spacefaring human culture, the Emergents, who are bent on conquest rather than trade. Now, however, the Qeng Ho, a band of human interstellar traders, have discovered the Spiders, an alien race poised to enter its own space age.

Although human beings have settled on dozens of worlds and created societies ancient enough to have achieved greatness and collapse several times over, only the most limited traces have been found of alien cultures. In this prequel to his Hugo Award-winning space opera, A Fire upon the Deep (1992), Vinge takes us to an era some thousands of years in our future, when humanity has just begun its exploration of intergalactic space and has as yet no inkling of the complex physics that rules the galaxy.
