Cod: A Biography of the Fish that Changed the World - Mark Kurlansky There is no way you could ever get me to eat cod, despite my partial Norwegian background where they eat a variety of disgusting fish dishes, the most famous being lutefisk, a kind of rotten, spoiled gelatinous mess. But I loved this book. Kurlansky is another John McPhee, supplying all sorts of interesting details. Turns out cod has been extremely important to civilization and almost as essential as bread. It was easy to fish and preserve and probably made discovery of North America by the Vikings possible. Fascinating.
