The story of a hundred year way that starts in 1940 and lasts so long no one remembers why it began. After a plague kills most of the society, small groups survive and finally reconnect to rebuild, until it grows so prosperous a new uprising begins again progress, claiming it is what starts wars in the first place.
It seems H.G Wells the author was a prophetic. He did predict a war would erupt in 1940, just a few months after world war two actually started in 1939.
