My guest this week says her first novels were fuelled by nostalgia and the past. She wrote them while living in a small market town in England, and harking back to her former homes in California and Ireland. Her soundtrack connects her back to those places and their people. Traditional emigrant songs that remind her of stoic characters in her family, while the gay anthem of La Cage Aux Folles is symbolic of friends in the LBGTQ community and her themes of loyalty and personal autonomy. There’s also a special place for the BBC shipping forecast, which she used to listen to in bed as a child, finding poetry in its strange names.  She is Orna Ross – and she’ll be here on Wednesday with her Undercover Soundtrack.
