On this month's show we welcome Laura Barnett and Kathryn Williams, talking about their remarkable collaboration on a world first - a novel with a specially-composed accompanying soundtrack. The book and album are called "Greatest Hits" and tell the story of the life of Cass Wheeler, a legendary singer-songwriter whose life was filled with highs and lows. We also review Harmless Like You by Rowan Hisayo Buchanan and have chat in the studio from novelists Mike Gayle and Catherine O'Flynn. ** _ _
