Fiona McConville is a child of the Western Isles, living on the Scottish mainland. City life doesn’t suit Fiona and at age ten she is sent back to her beloved isles to live with her grandparents. There she learns more about her mother’s strange ways with the seals and seabirds; hears stories of the selkies, mythological creatures that are half seal and half human; and wonders about her baby brother, Jamie, who disappeared long ago but whom fishermen claim to have seen.
