On an unnamed archipelago off Britain's east coast, women control the civic institutions, control the finances, run businesses, care for their children – and hope for a better world. It has been Eva Levi's life's work, but now that she has disappeared, the inhabitants fear it will be destroyed. But they don't know about Cwen, who has returned to haunt the civilisation. Her name has ancient roots, reaching down into the Earth and halfway around the world. The islands she inhabits have always belonged to women. And she will do anything she can to protect them. A portrait of female power and female potential, both to shelter and to harm. The author speaks to the supermodel-turned-activist Lily Cole.
