Book excerpt: Nora Okja Keller, the acclaimed author of Comfort Woman, tells the shocking story of a group of young people abandoned after the Korean War. At the center of the tale are two teenage girls—Hyun Jin and Sookie, a teenage prostitute kept by an American soldier—who form a makeshift family with Lobetto, a lost boy who scrapes together a living running errands and pimping for neighborhood girls. Both horrifying and moving, Fox Girl at once reveals another layer of war's human detritus and the fierce love between a mother and daughter.
