Khan Academy

This isn't a book, but a really cool website for learning things. Khan Academy is an online repository (my stupid computer says "online" isn't a word) of knowledge in the form of videos. It has videos on math, from addition to calculus and statistics and trigonometry, (which I have discovered is fun and not that hard), all ranges of science, lots of things I don't understand on finance and economy, and even a bit about humanities and civics and the like. Also, if you make an account, you can earn badges for doing things like getting a streak of 5000 trig problems right in a row (almost there!(no, I'm not)).

Note: I am not being paid to say this, but I should be :)

So if you have some spare time, check that out.
