Spaceflight Dynamics by William E. Wiesel is also a good book with a broader overview into much more topics, including attitude dynamics and rocket dynamics. As opposed to the BMW which only covers orbital motion, but in more depth. Orbital Mechanics by Prussing and Conway (of Laguerre-Conway fame) is also a very nice book, going into more details of advanced orbital motion, including some more modern methods. But damn, aerospace engineering books are really expensive. I've spent a small fortune on these books.
