A lot of books mentioned in the comments are great. But reading them just to read them isn't going to bring that much value. I get the most value out of programming books when I've been coding and I see place in my project and I think, "there has got to be a better way to do that." I then will search for specific chapters in books that help me improve what I think can be done better. To me it's better to use them as a reference while you are building something than just reading them cover to cover.
