The Last Marco Polo by Chen J. Ho

When Jack Wells, a young banker from New York City, disembarks in Shanghai—the Pearl of the Orient—in 1937, he has no idea that he is about to step into one of the most tumultous periods of Chinese history. On the eve of the Sino-Japanese War, Jack and a beautiful Chinese girl are brought together and beneath the bombs that fall on Shanghai and the Rape of Nanking, a sweeping love story unfolds.
