Farenhajt 451 by Ray Bradbury

In a future society where firemen burn books to suppress independent thought and maintain a superficial, media-saturated order, a fireman named Guy Montag becomes increasingly disillusioned after meeting a curious young neighbor and witnessing a woman choose to die with her books; his secret reading and growing doubts bring him into conflict with his superiors and lead him to flee and join a clandestine group of book-loving outcasts who memorize literature in hopes of preserving knowledge for a future rebirth.

The 16722nd greatest book of all time
