What she unearths is a tale of five feisty red heads struggling to climb out of poverty and find love through two world wars. It's a story full of surprises and scandal - a death in a workhouse, a son kept in a box, a shameful war record, a clandestine marriage and young, tragic deaths.

As she unravels the story of Nanna and her scarlet sisters, Helen starts to break the spell of the past, and sees a way she might herself find love again.
