My guest this week has always written in the grip of a wide-ranging playlist, but for one particular novel she found herself listening to three pieces intensively, maybe obsessively. In those songs she found her characters’ strengths and their more playful, softer sides, the great challenges they faced and the reserves they drew on to see them through. She is award-winning bestselling author, indie champion and women’s advocate Melissa Foster – and she’ll be here on Wednesday talking about Chasing Amanda and its Undercover Soundtrack.
