This city of the future encompasses two worlds: that of the hedonistic ruling class and that of a segregated subculture, toilers in a mechanized underworld who labor to provide the rich with their pleasures. When a charismatic leader arises, she seeks a savior to unite the disparate social orders. ""Between the brain that plans and the hands that build,"" she declares, ""there must be a mediator?the heart."" Thea von Harbou, creator of the screenplay for Fritz Lang's iconic 1927 film, wrote this novel to expand upon the movie's ideas and concepts. Vivid in description, rich in characterization and symbolism, the story draws upon ancient myths to form a compelling vision of the future. Noted science-fiction authority Forrest J. Ackerman hailed the book as ""a work of genius,"" and a century after its initial publication Metropolis continues to captivate readers.
