Was there a novel that helped shape your political views?

A lot of people, if asked, will say that Ayn Rand’s novels were tremendously important in shaping their political viewpoints.  Indeed, someone told me that Alan Greenspan cited Rand as one of his inspirations.

My question for you:  Have you read any novels that have played an important role in molding your p0litical beliefs?  I’m not asking about political tracts, or non-fiction books, or great speeches.  I’m curious only about the impact “novels of ideas” have had on people.

Off the top of my head, one of the novels that most shaped my views was George Orwell’s 1984.  His vision of a Leftist dystopia has always provided a “repression yardstick” for me.  I think that 1984 works so well because it’s not just a boring polemic with some plot thrown in for decoration.  Instead, it’s a dynamic story based upon a strong ideological foundation.

Interestingly, I find it impossible to think of any Leftist novel that affected me — I’ve always found them just as boring as Das Kapital itself is.
