The notion that "fire knows no borders" continues to ring true this summer. From Jasper, Alta. to Athens and the American West Coast... wildfires have left their marks on so many communities – and on the minds and memories of those who call them home. Viet Thanh Nguyen is a self-described scholar of memory. Much of the Pulitzer Prize-winning author's work examines how trauma shapes our narrative and emotional recollection. He speaks with Piya Chattopadhyay about his latest kids book Simone, which tells the story of a young girl and her mom fleeing home in the face of fire.
