Shortly after her thirteenth birthday, Ritva is sent away to Seili, an island in the far north of Finland. A former leper colony, Seili is now home to 'hopeless cases' - to women the doctors call mad. But Ritva knows she doesn't belong there. As biting winter follows biting winter, she longs to be near to her sister, and wonders why her father ever allowed her to be taken to this desolate place.

Hope arrives in the form of Martta, a headstrong girl who becomes Ritva's only friend. Martta is a Sami, from the north. All through her childhood, Ritva's mother told her wonderful Sami legends and tales - of Vaja the reindeer, the stolen sealskin, of a sacred drum hidden long ago. When Ritva and Martta decide to make their escape, this is where they will head.

So begins an odyssey over frozen sea and land towards a place where healing and forgiveness can grow. This is a story about friendship, about seeing the world through a different perspective, and the stories and tales that can make up a life.
