Since the beginning of the war in Afghanistan, thousands of people have been forced to flee their homes, joining the 43 million refugees who are currently displaced around the world. Khaled Hosseini, bestselling author of “The Kite Runner” and “A Thousand Splendid Suns,” feels a particular kinship with these refugees. In 1980, when he was a teenager, he and his family were granted asylum in the U.S. when Afghanistan faced a different decade-long war with the Soviets. Hosseini is currently a goodwill envoy with the UN Refugee Agency. He is also the founder of the Khaled Hosseini Foundation, which provides humanitarian assistance to the people of Afghanistan.
