A riveting, immersive account of the agonizing decision to use nuclear weapons against Japan—a crucial turning point in World War II and geopolitical history—with you-are-there immediacy by the New York Times bestselling author of Ike’s Bluff and Sea of Thunder. “As Christopher Nolan’s movie Oppenheimer shows, the shockwaves reverberate still.
