I probably don't agree with Rand about anything and I despise some of her ideas, but I still highly recommend two of her novels: Atlas Shrugged and The Fountainhead. Even if you end up rejecting her philosophy entirely, they still get you to do some soul-searching. And besides that, I make a point of exposing myself to things I disagree with. But, seriously, she writes good and substantial fiction. Even if you hate her, you will frequently find yourself enamored with her protagonists.
