Know any memoirs and novels that revolve around fascism?

Firstly, look at Animal Farm. It's a satire book by George Orwell and it talks about fascism in a satirical way. If you need something specifically dealing with post WWI fascism then in the range of fiction I don't know of any off hand but check out All Quiet on the Western Front, though it takes place from the point of view of German soldiers at the peak of WW I. (I think. It has been six years since I have read it)
