Dude, Where's my Country? by Michael Moore. I haven't finished even the first chapter, since I just started, but from what I see right now, he repeated quite a few of his points in Fahrenheit 9/11. I'm not saying any more than that, since it's gonna go into politics.
Other than that, it's got some good points. I wouldn't say it's a must-read, but it does make you ask some questions.
