'The Iron Heel' is Jack London's 1908 dsytopian novel about the rise of oligarchic tyranny in the United States. Playing upon the socialistic themes that were so prevalent at the beginning of the 20th century, 'The Iron Heel' tells the story of a wealthy class that squeezes out the middle class and effectively rules for three centuries until a revolution ushers in the 'Brotherhood of Man'. As important a commentary today as when it was first written, London's novel is a chilling depiction of a possible future world and an excellent exposition on the struggle between socio-economic classes.
