Author Mohsin Hamid and actor, writer and musician Riz Ahmed reflect on why stories of migration have captivated our imaginations.

From the Ancient Greeks to Hamid's most recent novel, Exit West, stories of migration and displacement, love and hope are necessary in dark times. Ahmed, who starred in the film adaptation of Hamid's novel The Reluctant Fundamentalist, joins the author to discuss how art and the novel can reflect a rapidly changing world.
