In Mark Kurlansky's book, the humble cod becomes a central character in world history. Europeans began crossing the Atlantic for cod—and it was cod that made such long voyages possible. Cod has fueled wars and revolutions, served as the staple diet of entire nations, shaped the economies of various countries, and contributed significantly to the colonization of North America. The author introduces readers to the people whose lives were closely linked to this unique fish—explorers, traders, writers, chefs, and, of course, fishermen. He recounts the cod wars of the 16th and 20th centuries, shares recipes from across the ages, and introduces us to the cod itself—its habits, evolution, and, ultimately, tragedy. Cod has fed humans for centuries, but now it needs their help: the seemingly inexhaustible fish stocks have been virtually depleted.
