Imagine the best teacher you've ever had. Not the flashy one who thinks he's god's gift to the field or always right. The one who's interesting because he has the quiet confidence of somone who has thought a LOT about a subject and cares passionately about ideas and their effects in the real world. And so he needs you really to understand and consider the points he's making.
Now imagine he's talking to you (well, almost, the narrator is good and not so far off) about something where, if you agree with him, there's a limited time to take concrete steps so that good ideas have the best chance of getting implemented in ways that will make the majority of people's lives a lot better.
If that sounds good, then get this book. Even if you disagree with some of it, unless you're Tom Delay and just want to go around bitch slapping people (or countries) who dare to contradict you, you will still take away a lot.
