Nanjing never cries

"Nanjing Never Cries is a historical novel set around the second Sino-Japanese War (1937 to 1945). It follows two MIT students, one born in Salem, MA and the other a Chinese exchange student, as they become best friends and advance through their careers. As professors, the two settle in Nanjing and are present for the horrific massacre that takes place there when Japan invades. One is killed; friends and family flee. The story concludes years later, as one of their protégés seeks justice in the arrest and, she hopes, execution of the Japanese soldier who killed her civilian father."--
