Grief-stricken and on the verge of a breakdown, Luda Managan and her two teenage children try to make a home for themselves on a collection of harsh and haunted Scottish islands. Luda, a photographer, is mesmerised by the extraordinary magic of the islands but soon finds herself condemned by the local community after publishing images documenting the death of a local child. Alienated, Luda turns her attention to the records from the 17th century island witch-hunts and the fragmented life stories of the executed women. Min, restless and strong, finds comfort in the depths of the North Sea and in an unlikely friendship with the elderly and irreverent local 'witch'. The only thing that Darcy cares about is getting entry into university - one far away from his mother. Until he meets the wild foundling, Theo.
