There are quite a few at the top of this list, and they vary based on subject. Are you speaking about technical books, or literature, or something else? Regardless, the one that I spent a good year reading through multiple times was Farnsworth's Classical English Rhetoric. A brilliant book that challenged my knowledge of rhetoric and enabled me to hone my rhetorical skills. You can read it to learn or read it just for the awesomeness of the passages. http://www.amazon.com/Farnsworths-Classical-English-Rhetoric-Farnsworth/dp/1567923852 http://www.amazon.com/Farnsworths-Classical-English-Rhetoric...
