The year is 2041. Since the end of the First World War, Berlin has been an enormous subterranean city, home to 300 million citizens who have never seen the sun and presided over by the autocratic Hohenzollern dynasty.
Every aspect of life is regimented; from controlled rations that are issued on the basis of work-for-food, to a press that works exclusively under the auspices of the Information Service.
Christianity has been abolished and all breeding is carried out on the basis of strict eugenic principles.
Lyman De Forrest, an American chemist, discovers a way of neutralising Berlin's defences and, assuming the identity of a dead German man, enters the city to discover its hidden truths.
The first outsider for decades to enter the forbidden metropolis, he is horrified to find a society where women are kept isolation in for breeding or the pleasuring of high status men.
Can De Forrest escape this living tomb? Published shortly after the end of the First World War, City of Endless Night is a tremendous example of early dystopian science fiction. Thought to have been the inspiration behind Fritz Lang's Metropolis, it has stood the test of time and is certain to appeal to modern readers.
