Dr. Chen Wei thought he was writing a history dissertation at Tokyo University. Then he found the archive that everyone said had been destroyed — classified documents proving Unit 731 conducted live human experiments on thousands of victims and was protected by a Cold War cover-up reaching from Washington to Tokyo. Now powerful people want him dead, his mentor has been murdered, and the only weapon he has is the truth. Hunted across three countries, Chen must outsmart intelligence agencies, expose a conspiracy seven decades old, and decide what he is willing to sacrifice to make the world remember what it chose to forget.
