In the first episode of The Write Song, Kat Kourbeti is joined by Kate Heartfield to talk about the music behind her book 'The Valkyrie', a Norse mythology retelling drawing on the story of the Valkyrie Brynhild, cast off from Valhalla and thrown into a love triangle in the midst of a bloody conflict—where her path diverges from the stories told before.
