An unparalleled work of historical conjecture, ranging imaginatively over huge tracts of the American popular consciousness, Don DeLillo's Libra contains an introduction by the author in Penguin Modern Classics.In this powerful, eerily convincing fictional speculation on the assassination of President John F. Kennedy, Don DeLillo chronicles Lee Harvey Oswald's odyssey from troubled teenager to a man of precarious stability who imagines himself an agent of history. When "history" presents itself in the form of two disgruntled CIA operatives who decide that an unsuccessful attempt on the life of JFK will galvanize the nation against Communism, the scales are irrevocably tipped.
