A very strange book. It's basically a series of short stories combined into one volume, but the characters are all connected in some ways and taken together they tell the story of how life on Earth was decimated by a plague and climate change and what people did afterwards. The final connections and the overarching narrative of the story doesn't become clear until the last chapter/story, which pulls everything together. It's also an exercise in memory, because the whole thing fits together like an intricate puzzle and if you aren't able to remember details you're going to miss a lot of the connections. It's an emotionally heavy story of an uncomfortably possible apocalypse and it made me tear up quite a few times, but also didn't quite have the emotional impact I think it could have had because I was so busy trying to keep track of how all the different stories fit together and place them in the timeline and the overarching narrative. However, I have a notably terrible memory, so that may be less of a problem for other people. It's unusual and clever, an interesting story told in a unique way, and worth the read if you like apocalypses with a sci-fi edge or if you just want a book unlike anything you've read before.
