1984

“It was a bright cold day in April, and the clocks were striking thirteen.”

It's an alternate world and it's not a pretty one. Our main character, Winston, is a party official in a totalitarian world:

“War is peace.
Freedom is slavery.
Ignorance is strength.”

Big Brother is always watching. Winston is not totally under the thumb of Big Brother, however; soon he is sought as a “thought criminal,” for his acts of insurrection that include such simple acts as keeping a journal and thinking for himself.

And always 1984 will remain as a warning, a caution, a reminder.
