A classic novel of known space
Phssthpok the Pak had been traveling for most of his thirty-two thousand years. His mission: save, develop, and protect the group of Pak breeders sent out into space some two and a half million years before . . .
Brennan was a Belter, the product of a fiercely independent, somewhat anarchic society living in, on, and around an outer asteroid belt. The Belters were rebels, one and all, and Brennan was a smuggler. The Belt worlds had been tracking the Pak ship for days—Brennan figured to meet that ship first . . .
He was never seen again—at least not by those alive at the time.
