Absorbing ... [Hawley] is a fluent explainer of complex subjects ... The story barrels ahead urgently ... Duty, anger, sorrow, conscience and even hope mix together to form the novel’s bracingly intimate ending.
Engrossing and thought-provoking ... The plot feels entirely plausible, and none of the characters fit any obvious stereotypes ... The author’s research is impressive as he describes how the bomb is designed to work, the tensions within the Japanese power structure, and details of Japanese culture.
