Author Kent Matsumoto's parents both lived through traumatic experiences during WWII: his mother was forced into an internment camp for Japanese-Americans in the U.S., and his father survived the atomic bombing of Hiroshima. In a new novel, Of White Ashes, Matsumoto and his wife and co-writer Constance Hays Matsumoto explore a romance between two Japanese-Americans based on Matsumoto's parents. They spoke with Here & Now's Celeste Headlee about choosing to fictionalize true events, and how writing together created a love story of their own.
