We / Yevgeny Zamyatin ; [translated by Mirra Ginsburg].

Enhanced descriptions from Syndetics:

Yevgeny Zamyatin's page-turning science fiction adventure, a masterpiece of wit and black humor that accurately predicted the horrors of Stalinism, We is the classic dystopian novel that became the basis for the tales of Aldous Huxley, George Orwell, and Margaret Atwood, among so many others. Its message of hope and warning is as timely at the beginning of the twenty-first century as it was at the beginning of the twentieth.

In the One State of the great Benefactor, there are no individuals, only numbers. Life is an ongoing process of mathematical precision, a perfectly balanced equation. Primitive passions and instincts have been subdued. Even nature has been defeated, banished behind the Green Wall. But one frontier remains: outer space. Now, with the creation of the spaceship Integral, that frontier -- and whatever alien species are to be found there -- will be subjugated to the beneficent yoke of reason.

One number, D-503, chief architect of the Integral, decides to record his thoughts in the final days before the launch for the benefit of less advanced societies. But a chance meeting with the beautiful 1-330 results in an unexpected discovery that threatens everything D-503 believes about himself and the One State. The discovery -- or rediscovery -- of inner space...and that disease the ancients called the soul.
