About the book (from Wikipedia):
Nineteen Eighty-Four, often published as 1984, is a dystopian novel by English author George Orwell published in 1949. The novel is set in Airstrip One (formerly known as Great Britain), a province of the superstate Oceania in a world of perpetual war, omnipresent government surveillance and public manipulation, dictated by a political system euphemistically named English Socialism (or Ingsoc in the government’s invented language, Newspeak) under the control of a privileged Inner Party elite, that persecutes individualism and independent thinking as “thoughtcrime”.
The tyranny is epitomised by Big Brother, the Party leader who enjoys an intense cult of personality but who may not even exist. The Party “seeks power entirely for its own sake. It is not interested in the good of others; it is interested solely in power.” The protagonist of the novel, Winston Smith, is a member of the Outer Party, who works for the Ministry of Truth (or Minitrue), which is responsible for propaganda and historical revisionism. His job is to rewrite past newspaper articles, so that the historical record always supports the party line. Smith is a diligent and skillful worker but he secretly hates the Party and dreams of rebellion against Big Brother.
As literary political fiction and dystopian science-fiction, Nineteen Eighty-Four is a classic novel in content, plot and style. Many of its terms and concepts, such as Big Brother, doublethink, thoughtcrime, Newspeak, Room 101, telescreen, 2 + 2 = 5 and memory hole, have entered into common use since its publication in 1949. Nineteen Eighty-Four popularised the adjective Orwellian, which describes official deception, secret surveillance and manipulation of recorded history by a totalitarian or authoritarian state. In 2005, the novel was chosen by TIME magazine as one of the 100 best English-language novels from 1923 to 2005. It was awarded a place on both lists of Modern Library 100 Best Novels, reaching number 13 on the editor’s list, and 6 on the readers’ list. In 2003, the novel was listed at number 8 on the BBC’s survey The Big Read.
