I’m not totally sure why I picked this up after I found Three Body Problem sort of dense and difficult. I think it’s because I really liked the central plot idea. *something happens* and everyone over the age of 13 dies.How does civilization go on? Well as it turns out, it’s easier in China because there’s basically an AI that helps. And so the central part that I was the most interested in gets handwaved away a little bit (you get some foreshadowing in the form of author notes that things are going to ok and humanity doesn’t die off) and then the rest has a lot more to do with global politics. And to me the logistical parts and the human stories are what is interesting. To the author, there was clearly one part--a massive Antarctic War--that occupied way more of the story than it should have if it was just one plot device. Took me getting to the Afterword by the author before he admits that the Child War was the first thing that convinced him to write this book. It was obvious once he said it. So, I think certain people would like this book, I liked it enough to finish it but not enough to look back on my time investment in it.
