The Eon Series: Legacy, Eon, and Eternity

A three-volume science fiction saga by Hugo and Nebula Award–winning author Greg Bear, exploring parallel universes and the consequences of creating an alternate reality that transcends time and space. Legacy serves as a prequel, following an agent of the Way—a man-made tunnel through multiple dimensions—as he pursues a renegade fanatic and his four thousand followers to a world inhabited by flora/fauna hybrids, where he becomes caught in a devastating civil war. Eon takes place in a volatile twenty-first century amid escalating nuclear tensions. A hollowed-out asteroid suddenly appears above Earth, containing the remains of Thistledown, an abandoned city built by survivors of a nuclear holocaust. Scientists race to understand the asteroid's secrets before an impending apocalypse destroys humanity. Eternity depicts Earth as a nuclear wasteland. An asteroid-starship orbiting the planet houses Thistledown's civilization—humanity's descendants—who have spent decades attempting to restore their world. With finite resources, they seek to reopen the Way, a gate that could benefit both Earth and allow the asteroid's residents to return home. The trilogy combines humanistic themes with cutting-edge science and speculative extrapolation.
