We (Yevgeny Zamyatin)

Yevgeny Zamyatin's We, from 1921, is the original dystopia that spawned all other twentieth-century dystopias portrayed in literature. Despite being the oldest dystopia, it is in some ways the most relevant one for today, more so than the more famous 1984 and Brave New World. Yet its most crucial lesson is almost always ignored.
