In the near future, climate change and a global pandemic have decimated the human race, leaving just a few scattered communities still alive and next to no children being born (literally — fertile women are so rare that they're commodities easily kidnapped and thus guarded closely). Given this drastic change, a project originally created to send people to off-world colonies has shifted focus to try sending people 10,000 years into the future in the hopes of re-establishing the human race. And that takes us to this book's second storyline: a scientist from that group has awoken sometime around the year 11,000 AD, and is trying to find some sign of other humans in the vast, environmentally reclaimed world.
Told in alternating timelines between the near future and far, far distant future, this is an interesting take on climate fiction, showing that it's not the world so much as humanity that's suffering from what we've done to the planet. That said, it's also really questionable that the scientists who see what we've done would think that yeeting a human 10,000 years into the future to restart the destructive species is a good idea, which makes that whole premise pretty hard to buy. Between that and a few other problematic choices by the scientists, I'm inclined to think of this as an OK thought experiment, but not a particularly great book.
