Greg Bear can think BIG. Eon is his classic tale of an asteroid that arrives in orbit around the earth. The asteroid is revealed to be simply one endpoint for an endless (?) corridor named The Way. Inside The Way is the city of Thistledown, populated by humans. That human civilization is thousand of years old. Thistledown is the future, and the past. Greg Bear knows how to describe his quantum mechanics, and the non technical reader should not be intimidated. The characters and intrigues of the various factions, as well as the strong characters and fabulous descriptions all combine in a marvelous story.
The sequel, Eternity, is about how mankind must give up it’s manipulation on space-time. After the message of hope brought by the first novel, it is interesting how in Eternity Bear takes humanity back down a notch, not closing the door to the future but simply reminding us that the gods do not take kindly to hubris. And through it all, Bear’s astounding imagination is combined with a gift for good, clear and interesting prose.
