I have read three of these books: Cod, Salt and Zero. They were all good. I liked Zero the best. Interesting tidbit: Some ancient cultures found the abstract idea of nothingness to be so alien that they didn't even have zero in their number system. It makes sense if you think about it. And then you start to realize the mysterious, terrifying power of 0!!
Nancy Pearl also has an intriguing list of best spy novels. I'm thinking of choosing her No. 1 pick, Tinker, Tailor, Soldier, Spy by John le Carre, for my book group, as an eclectic change of pace.
