Long Joanne Harris, the multi-million selling author of Chocolat, discusses her new novel, The Gospel of Loki, inspired by the Norse god of trickery, mischief and deception, a shape-shifter whose cultural manifestations range from 13th-century legends to Marvel comics and video games. She’s joined by Radio 3 New Generation Thinker Eleanor Rosamund Barraclough. They debate the enduring power of Norse mythology in conversation with Free Thinking presenter Anne McElvoy recorded in front of an audience at the Free Thinking Festival at Sage Gateshead and broadcast as part of The Northern Lights season.
