Bertrand Meyer's Object-Oriented Software Construction. A classic, written in an engaging style that makes the book very readable and conveys important ideas about programming and software engineering (and object-oriented thinking too!). The first edition was perfect. The second edition exploded in size and I never read the full book; I dipped in and read several sections and they were pure Bertrand Meyer, so I have no doubt the second edition is as good as the first, just longer. The book was published c. 1990, but it's a classic for good reason and would be just as useful now as it was then. Also, as jes noted in another comment, SICP (Structure and Interpretation of Computer Programs) is a must-have and must-read.
