Four years after Bonnie Prince Charles had lost the battle of Culloden Moor, he and his friends are planning another Rising.

The Duke of Arkrae, Chief of the Clan MacCraggan, is of great importance, owing to the strategic position of his territories. But where his sympathies lie is known neither to the Jacobites nor to the English.

Iona, the lovely red-haired ward of a Jacobite exile in Paris, agrees to impersonate the Duke's half-sister, who was drowned as a child, in order to discover the truth. Her thrilling adventures, and how she herself finds love, are all told in this exciting tale set in the Scottish Highlands of 1750.
