I haven't heard of The Wanting Seed. I'll have to check that out.
Two books that are not on most people’s reading list are “It Can’t Happen Here” by Sinclair Lewis and Darkness at Noon by Arthur Koestler.
While Lewis “plots” the totalitarian takeover of America by a “republican”, the methods he describes are being used today. He shows that it Can and IS happening today.
Darkness at Noon is just plain scary.
Rand’s We the Living is also good reading during this time in history.
