A dystopia is a fictional world where people live under a highly controlled, totalitarian system. In his novel "Brave New World," Aldous Huxley created a dystopia where individual identity is suppressed and families no longer exist.
The word dystopia comes from adding the Latin prefix dys, which means “bad,” to the word utopia. So a dystopia is a utopia gone wrong. While the intention might have been to create a perfect society, all the regulations make life there really bad. Often a dystopia in a book is a society of the future, serving as a warning about what might happen if we let technology, industry, and government creep further and further into our lives.
