Need Lisp book recommendation

So I used Lisp for an assignment I've just completed where we got the choice of using any language we wanted to. I decided to use Lisp even though I hardly knew it, as it seemed like a problem that was good for a language like Lisp.

I liked it so much that I'd actually like to learn it properly. As I learn better from reading books than online resources, I want to get a suitable book for learning Lisp that would also be a good general reference.

You guys are the geekiest community I know, soooo, any suggestions?
