The Iron Heel is a political novel in the form of science fiction by American writer Jack London, first published in 1908.
The story proper begins with Avis Everhard, a daughter of a renowned physicist, John Cunningham, and future wife of socialist Ernest Everhard. At first, Avis Everhard does not agree with Ernest's assertion that the whole contemporary social system is based on exploitation of labour. She proceeds to investigate the conditions the workers live in and those terrible conditions make her change her mind and accept Ernest's worldview. Similarly, Bishop Morehouse does not initially believe in the horrors described by Ernest but then becomes convinced of their truth and is confined to a madhouse because of his new views.
