Don DeLillo's mesmerizing novel was a major bestseller when it was published in 1997 and was the most widely reviewed novel of the year. It opens with a legendary baseball game played between the Brooklyn Dodgers and the New York Giants in 1951. The home run that won the game was called the Shot Heard Round the World, and was shadowed by the terrifying news that on the same day, Russia tested its first hydrogen bomb. Underworld then tells the story of Klara Sax and Nick Shay, and of a half century of American life during the Cold War and beyond.
