On a stormy winter's night on a remote island in the wild North Atlantic, something draws Marie down to the beach, where she finds a small girl, barely alive. Who is she? How did she come to be there? The mystery grows, because nobody on the island seems to know of a missing child.

When Marie meets Malcolm, who is returning to the island after years away, the two team up, and together they try to solve the mystery. Perhaps romance is inevitable, but the discovery of a group of climate refugees, hidden away near one of the most remote beaches, is the last thing the two expect. Nor is it clear how these strangers come to be there, and who is controlling them, or why. In the company of a local police officer and an absurdly young minister of the kirk, the friends unearth the secret of the refugees, and the villains who have held them there for so long. But discovering the truth is not the same as freeing the people, a task that nearly costs them their homes and their lives.

Dark Waters is rich in the culture of the island, En-Somi. The customs are ancient, the dialect unique, and the story has a wealth of characters of all ages, from young Marigold, a daughter of one of those held in slavery, or Frankie, the leader of the refugees, to the ancient bard, Olaf. Pick up this novel and you will find it hard to put it down again, and when you have read it, you will find it easy to believe that you have actually been there.
