It Can’t Happen Here, by Sinclair Lewis, 1935. ISBN 0451465644.
This story tells how fascism could come to America. Lewis wrote it in 1935 – before Hitler attacked Poland in 1939. It shows that it was not too early to predict the rise and some of the consequences of fascism. I was surprised that both television and concentration camps were mentioned. Much of it still rings true to me, how an anti-intellectual streak fueled by class resentment could revive fascism in the US.
