Do Androids Dream of Electric Sheep - Blade Runner 1 by Philip K. Dick This masterpiece was ahead of its time, a prescient rendering of the dark future, and the inspiration for the blockbuster film Blade Runner By 2021, the World War has killed millions and wiped out entire species, causing mankind to disappear from the planet. People who do not own a living creature covet any possible animal, and companies built realistic simulations of horses, birds, cats, and sheep for those who can't afford them. Humans have even been created. People who move to Mars are greeted by androids so advanced that they cannot be distinguished from real humans. The government bans these artificial humans from Earth out of concern for their havoc-causing abilities. Androids living undetected among humans are driven into hiding. Deckard is commissioned by the government to find and retire rogue androids. In any case, androids will fight back with lethal force if cornered.
