Book 2 in Eon series (1988)
Publisher: Open Road Media
A visitor from the end of time comes to take a handful of strangers into space, where they must destroy the ultimate marvel of science in this powerful sf classic.
In Eternity, Greg Bear returns to the Earth of his acclaimed novel Eon–a world devastated by nuclear war. The crew of the asteroid-starship Thistledown has thwarted an attack by the Jarts by severing their link to the Way, an endless corridor that spans universes. The asteroid settled into orbit around Earth and the tunnel snaked away, forming a contained universe of its own.
Forty years later, on Gaia, Rhita Vaskayza recklessly pursues her legacy, seeking an Earth once again threatened by forces from within and without. For physicist Konrad Korzenowski, murdered for creating The Way, and resurrected, is compelled by a faction determined to see it opened once more. And humankind will discover just how entirely they have underestimated their ancient adversaries.
