Bailey Cove Sci-Fi: Do Androids Dream of Electric Sheep?

By 2021, the World War had killed millions, driving entire species into extinction and sending mankind off-planet. Those who remained coveted any living creature, and for people who couldn't afford one, companies built incredibly realistic simulacrae: horses, birds, cats, sheep. . . . They even built humans. This novel is the inspiration for the movie "Bladerunner."
