This is a remarkable science fiction novel. It’s quite a story, quite a work of imagination.
What happens is that human beings have been screwing up the Earth to the point that it’s becoming uninhabitable. One response has been to try to create Earth-like conditions on planets in distant solar systems. It’s hoped that these planets will eventually become new homes for humanity.
The terraforming work on one such planet is sabotaged at the last moment. This leads to an enormous unintended consequence: some of the planet’s spiders rapidly evolve, becoming bigger, smarter and much more sociable than the spiders back on Earth.
Before the Earth becomes uninhabitable, giant spaceships are launched with thousands of people aboard. Most of the passengers are stored away as “cargo”, hibernating in an unconscious state, waiting to be resuscitated when their ships finally reach inhabitable worlds, many years in the future.
Throughout the book, the author switches back and forth between what’s happening to the spiders on their planet and what’s happening to the people in one of the spaceships. I felt closer to the people, but the author does a wonderful job explaining things from the perspective of the spiders. As you’d expect, the two species eventually meet.
Somebody is supposedly trying to turn Children of Time into a movie. It really deserves a TV series, possibly with multiple seasons. The author has also published a sequel, Children of Ruin. It’s probably remarkable too.
