Octavia Butler's The Parable of the Talents
Oh good gravy, Octavia Butler was a prescient woman. In the second Earthseed book, the daughter of the protagonist from the first book is piecing together her mother's writings and philosophies--while chronicling the rise of a white supremacist/evangelical/tyrannical presidential candidate who talks "of making America great again." There is a line like "Their leader has come to power. They have acquired...if not legitimacy, at least a shadow of sophistication." Ugh. This book would have been hard to read even in better and less frightening times, but reading it now was honestly horrifying and I just found parts of it to very upsetting. And that's not even getting into the fairly tragic mother-daughter story. This was so good but it REALLY bummed me out. A-.
