Nick Shay and Klara Sax knew each other once, intimately, and they meet again in the American desert. He is trying to outdistance the crucial events of his early life, haunted by the hard logic of loss and by the echo of a gunshot in a basement room. She is an artist who has made a blood struggle for independence. Don DeLillo's mesmerizing novel opens with a legendary baseball game played in New York in 1951. The glorious outcome -- the home run that wins the game is called the Shot Heard Round the World -- shades into the grim news that the Soviet Union has just tested an atomic bomb. The baseball itself, fought over and scuffed, generates the narrative that follows. It takes the reader deep into the lives of Nick and Klara and into modern memory and the soul of American culture -- from Bronx tenements to grand ballrooms to a B-52 bombing raid over Vietnam.
