In this sequel to EON, the Way is a tunnel through space and time that leads to other worlds; some very similar to earth. It's a most formidable discovery and with such an important find comes disputes as to the nature of the Way and how it should be used.
"In "Legacy"'s predecessor, "Eon" (1985), part of Earth's population escaped a nuclear war by traveling through time along a path called the Way. As the sequel commences, the Way has been in use for some time, and dissidents have found ways to drop out more thoroughly than a"ny 1960s hippie ever did. One such dropped-out group consists of 4,000 antitechnological Naderites, to whom a troubleshooter named Olmy is dispatched. He finds them on a settled, Earthlike world and their society taking a host of radically different directions, all of which Bear works out with his accustomed literacy, scientific accuracy, and deft characterization. As much an exercise in world building and social experimentation as a conventional story, the novel will not disappoint "Eon"'s fans and, since Bear really keeps it moving, stands well enough to be read on its own."
