Book recommendation from this morning: import

There was a book that was recommended today on the show by Thom. He said, it was pivotal. Something that was important, really a political work, but not specifically political. I can't think of a good illustration of this. Maybe an environmental book, like Silent Spring? I think it had only one word in the title, or the title was very short. I was busy at the time and couldn't write it down. I'm coming up with a blank now. Anyone have any ideas?  (jstir@comcast.net)  Thanks!
