Oh my god this was stunning. Major shoutout to my local library's reading challenge because I never would've gotten around to this one if it weren't for the nature writing prompt. Everything about this was just impeccably done. Reading this in late October was weirdly perfect because this is a book that needs to be read in the cold, but it's also so dark and depressing that I would advise against reading it in January or any of those other months that are hard enough to survive as it is. I'm scarfing down my dinner right now as I write this because I was so enraptured by the story that I forgot to eat. I was initially concerned that this book would take too political a stance (not that science is inherently political, but you know what I mean) but politics aren't even mentioned once. We are already in the midst of the mass extinction in this book-- it's not something to be debated anymore, but fact. The way it's written is so clever too. There is no technology or other references that could date it. This could easily take place 10 years ago, today, or 100 years in the future. And that in itself is a caution. Ugh even with how dark this was I just loved it.
