The second edition of the Obsessions book series is on the arts and crafts made by Japanese Americans held in U.S. concentration camps during World War II. All That Remains is a sequel to Delphine Hirasuna's 2005 book titled The Art of Gaman: Arts and Crafts from the Japanese American Internment Camps, 1942–1946. While working on that book, she spent many hours reflecting on why people banished by their own country to barrack encampments fenced in by barbed wire and guarded by soldiers with rifles pointed at them would take up art with such a fervor that it became an obsession to them.
