Solar Federation by S E Mulholland
I read the authors other novel Blindspot prior to this so this wasn't what I expected. Very climate fiction oriented, with one storyline about a young girl from Tajikistan going to university "5 minutes into the future" and the second storyline is some centuries from now. I generally avoid climate fiction as I find it a bit depressing, however this novel was really really good, super well thought out from an ecology viewpoint. How the effects of human society would be felt even centuries and millennia after it's disappearence. My favorite part was towards the end when a "unsympathetic military AI" takes control of a group of humans through their implants to break a mutiny. The AI is unsympathetic because it doesn't care about what happens to the humans it controls. Some lovely body horror. I definitely recommend this book
