In 1935, Zhou Ke, a modern history graduate student, transmigrates to Shanghai in the Republican era and is swept into the treacherous world of espionage, embarking on a decade-long life undercover.
He takes on multiple identities, including underground Party courier, confidential secretary for the Military Statistics Bureau, and cultural adviser to the Japanese. Caught between the Japanese and their puppet regime, the Military Statistics Bureau, and the underground Party, he uses book lists as codes and patience as a shield, risking his life to pass intelligence and protect a glimmer of hope. The devastation of the Battle of Shanghai, the bloodshed of the notorious No. 76 compound, and the grief of losing comrades never extinguish his original convictions. The trust placed in him by his mentor, the silent farewell of a confidant, and the faith of a friend who shares life and death become his strength as he presses on through the darkness.
From the first stirrings of spring in Shanghai to the break of dawn, from the fall of the isolated city to Japan’s surrender, he searches for himself amid his many identities and holds fast to his faith at the edge of humanity’s limits. Through ten lonely years, he never stands in the light, yet with solitary courage he wins a glimmer of dawn for his people, writing with his youth and blood the story of an unsung spy’s devotion and honor.
