"Logicomix: An epic search for truth" [1] is a graphic novel that chronicles the life of Bertrand Russell (logician and philosopher) and his interactions with legendary thinkers like Gottlob Frege, David Hilbert, and Kurt Gödel. I really enjoyed this. It was fun and highly educational.

Very heavily seconded. One of my favorite novels, it does a really good job of giving a "feeling" of mathematics, without including any actual mathematics.

This is the same author as Logicomix, which is aslo very highly recommended - a comic about logic, Godel, and the foundations of mathematics.

I really enjoyed Logicomix, a self-aware graphic novel mostly revolving around Bertrand Russell (with appearances by Godel, Wittgenstein, etc.) http://www.amazon.com/Logicomix-An-Epic-Search-Truth/dp/1596...
