Scottish Hebrides, Autumn 1373. The eight year old grandson of the powerful Lord of the Isles vanishes on the windswept island of Colonsay, and rumors fly that he has been spirited away by the faerie. Muirteach MacPhee investigates but he suspects the boy's disappearance has more to do with human greed and the mysterious piece of gold the lad found before he vanished. Muirteach scours the island, finding nothing except some hidden bones and an old man out looking for a lost goat. Mariota Beaton arrives from Islay to aid Muirteach in his search, but the lovely healer struggles with demons of her own.
