The iron heel - Jack London

Written in 1906, The Iron Heel is Jack London's terrifying
and visionary novel of a society where social revolution is brutally
crushed by The Oligarchy, a vicious state machine constructed to
destroy and enslave all resistance and opposition to market forces.

The Oligarchy was London's prophetic vision of what would later become fascism. In opposition to the dictatorship, Everest Everhard and the underground organise in what seems like increasingly futile odds.

The Iron Heel transcends genre juxtaposing science
fiction, social polemic, and timeless romance. But most significantly,
it serves as a warning - unheeded at its time of publication - which is
as relevant today as when it was written.
