Jack London 
The iron heel 

The Iron Heel is a dystopian novel by American writer Jack London, first published in 1908.
Generally considered to be "the earliest of the modern dystopian" fiction, it chronicles the rise of an oligarchic tyranny in the United States. In The Iron Heel, Jack London's socialist views are explicitly on display. A forerunner of soft science fiction novels and stories of the 1960s and 70s, the book stresses future changes in society and politics while paying much less attention to technological changes.
The book is unusual among London's writings (and in the literature of the time in general) in being a first-person narrative of a woman protagonist written by a man. Much of the narrative is set in the San Francisco Bay Area, including events in San Francisco and Sonoma County.
