George Orwell 
Nineteen Eighty Four 
Big Brother is Watching You

Orwell’s brilliantly bleak future vision of totalitarianism is arguably the greatest of all literary dystopias. Both in its impeccably realised world-building and the prophetic nature of its many ideological concepts, Nineteen Eighty-Four contrived to look back to the Stalinist purges of the 1930s whilst simultaneously predicting with uncanny accuracy the worst excesses of the Cold War-era Soviet Union. A textbook example of a novel you really must read.
