Chemistry Books for the Smart?

enzyme asks: "A couple of weeks back, chrisd asked for recommendations on computer books. This made we wonder: What are the great chemistry books? I want to know what books the chemistry geeks recommend! What are good books on chemistry - textbooks, popular science...whatever! Anything that an intelligent person without a PhD in chemistry can comprehend. What can I read to help me understand chemistry - my old chemistry textbooks don't really do this."
