In the 22nd century, the people of Earth made a pact with this far-flung civilization—all of the Makers’ intelligence in exchange for help in their mission. Three hundred years later, descendants of the original Procyon expedition have returned to Earth in a starship. They find a world that has forgotten the generations-old contract. 1985 Del Rey Book Condition is Acceptable: This used book shows wear to edges and cover, creases to cover and spine, stamped, writing inside, and some yellowing of pages.
