Life of Pi - Yann Martel
Despite coming with several recommendations, I have to say that I agree with the person who lent me the book, Chad McCleary, that it was a good book but did nothing to make me believe or not believe in God. I may want to re-read it when I am less tired; maybe I missed the point. Or perhaps I am not on the same literal plane as the author. I truly enjoyed the language and discriptions. For an interesting diversion, you might like Life of Pi movie.
