In his 2017 Pulitzer Prize-winning novel and New York Times number one bestseller, Colson Whitehead reimagined the metaphorical Underground Railroad of history – whereby slaves were transported under cover of night from one safe house to the next, bound for free land – and replaced it with an actual train. Luminous, furious and wildly inventive, Colson’s seventh book has been lauded by Barack Obama and Oprah Winfrey. He sits down with New York Times Book Review editor Pamela Paul to discuss his imaginative exploration of the foundational sins of America.
