Part science fiction, part dystopian fantasy, part radical socialist tract, Jack London's The Iron Heel offers a grim depiction of warfare between the classes in America and around the globe. Originally published nearly a hundred years ago, it anticipated many features of the past century, including the rise of fascism, the emergence of domestic terrorism, and the growth of centralized government surveillance and authority. What begins as a war of words ends in scenes of harrowing violence as the state oligarchy, known as "the Iron Heel," moves to crush all opposition to its power.
