Using a combination of firsthand accounts of Japanese A-bomb survivors, American aviators, and classified documents of government officials, Pellegrino (The Jesus Family Tomb
) reconstructs two horrifying days and their aftermath when the age of atomic warfare was introduced over Japan. He is fascinated with the “strange alchemy” of these cruel weapons (“One ten-millionth of a second later, a sphere of gamma rays escap[ed] the core at light speed”) as the bomb fell on Mrs. Aoyam tending her garden at Point Zero, literally before she could see it coming. Pellegrino is equally interested in the grotesque effects the blasts in Hiroshima and Nagasaki inflicted on the human body with its gamma rays, neutron spray and poisonous black rain. The stories of the few Japanese survivors includes a group of 30 civilians fleeing from Hiroshima to Nagasaki where they arrived to endure the second bomb, are heart-stopping. Pellegrino dissects the complex political and military strategies that went into the atomic detonations and the untold suffering heaped on countless Japanese civilians, weaving all of the book's many elements into a wise, informed protest against any further use of these terrible weapons. 16 pages of b&w photos, maps.
