New York Times best-selling author Julia Flynn Siler takes us deep into the story of the women who fought slavery in San Francisco's Chinatown with her new book, The White Devil's Daughters. The Writers Grotto's Bonnie Tsui, author of the award-winning American Chinatown, talks to her about the meticulous research and care required to pull together revelations about the trafficking of young Asian girls that flourished in San Francisco during the first hundred years of Chinese immigration (1848-1943), and the “safe house” that became a refuge for those seeking their freedom.
