In this powerful, eerily convincing fictional speculation on the assassination of 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 the president will galvanize the nation against communism, the scales are irrevocably tipped.
