Nikola Tesla -- fiction
RASL: The Drift deals with alternate universes. Worlds that are just like this one, with only the slightest differences. Looking for those small clues is sometimes helpful, sometimes upsetting, and this is especially true if you are not entirely sure what dimension you are in.
"The year is 1943, and famed inventor Nikola Tesla lives quietly in a New York hotel with his memories and his pigeons. However, when an inquisitive chambermaid discovers Tesla's personal papers, she and Tesla form an unlikely bond with far-reaching consequences. The narrative, which relies heavily on interior monolog, alternates between Tesla's personal history and the secret longings of others who were strongly influenced by the great man's inventions."
