Fahrenheit 451 by Ray Bradbury
"Fahrenheit 451" is the story of the awakening of Guy Montag. He's a fireman in a society where a fireman's job is to burn houses and the books in them. Slowly Montag becomes curious about why people would defy the law to keep the forbidden items. People are expected to spend their time in front of the television walls.
Montag accidentally reads a line in a book during a burning. Soon he has several books hidden in his house. And he meets an old man and a young girl who gives him the courage to think...something that is frowned upon.
