Wrapping up the Time Odyssey trilogy—according to the publishers anyway. The book’s contents speak otherwise.
In Time’s Eye (2004) one version of planet Earth was split into segments, then reassembled, with each segment from a different epoch. In Sunstorm (2005) another Earth defended itself against a gigantic solar flare. The enigmatic alien Firstborn, having caused both baffling events, intend to wipe out intelligent life, so that they can do—well, whatever it is they want to do, billions of years hence, without interference. This time, Sunstorm scientists note another object drifting toward Earth: a Q-bomb, a device powered by dark energy, peculiar stuff that (according to current real-world theories) powers the accelerating expansion of the universe. Athena, an artificial intelligence launched into space, finds a home, and reports back that Earth isn’t the only planet to have suffered the aliens’ malevolent attentions. Meanwhile, Bisesa Dutt, having survived on both Earths, wakes from a 19-year hibernation and hurries off to Mars, where scientists have discovered an Eye trapped in the polar ice by a Martian civilization billions of years ago. Bisesa has a curious affinity for the Eyes, enigmatic spheres by which means the Firstborn keep tabs on developments. The Eye sends her to Mir, the reassembled Earth, where a flabby, aging Alexander the Great is busy trying to conquer the patchwork planet. Various other characters wander about the cosmos, by space elevator, ion drive and whatever, each peregrination described in full scientific detail.
Readable, but more science travelogue than science fiction—and if you were anticipating a conclusion, or at least an alien encounter, forget it.
