1905. Christy has always dreamed of making the journey from her home in Tasmania back to the wild and beautiful Scottish island where she was born - the Isle of Skye, nicknamed 'cloud island' by the Old Norse people - to once again lay eyes on the tumbling waterfalls and dramatic coastlines of her homeland. And now, in her sixty-fifth year, Christy has finally decided to go, her mistrustful daughter Anne and beloved granddaughter Kathryn acting as companions. But what Anne and Kathryn don't realise is that Christy's past is darker and more textured than they could know, and that in returning to Skye they will unearth bittersweet memories long-buried - memories that will ultimately change the course of the three women's lives forever.
