Ian McMillan is joined by some of the most dynamic writers taking part in the Hay Festival: Michael Morpurgo, one of the nation’s best-loved children’s authors and author of ‘War Horse’, columnist and best-selling feminist chronicler Caitlin Moran, and the award-winning Cameroonian American novelist Imbolo Mbue. They’ll be discussing the stories that change us, and offer hope of change - and explore how we tell stories about ‘change’, be it ecological, emotional or physical.
