For me, the best dystopian books make me feel sadness because everything is so terrible. 1984 crushed my soul, especially with the twist. This book makes me feel sadness as well, but in a different way – sadness for the way things could have been, how the world could have eventually been a better place if the Brotherhood of Man actually existed.
If you’re looking for a story, though, I advise you to skip this. There’s a little story, but not much. If you’re looking for a political manifesto, also skip it, because again there’s not much. If you’re looking for some sort of combination of both of those, though, then this might be what you’re after.
