3.5! I really really enjoyed how civilization was portrayed before and after the Georgia Flu, especially the lack thereof post-plague. Reading this book has given me a lot to think about in life. I find myself stopping and wondering “What if?” As someone who has studied world history, the rise of civilizations, the fall of empires, the beginning of the modern age, I genuinely felt shaken to the core while reading; the author truly made this apocalyptic world eerily realistic, and that was definitely the strongest part of the novel.
