Among the misty lochs and glens of ancient Scotland, duty wages war against love on the battlefield of opposing cultures, religions, and political agendas.
After Caledonia's devastating loss in the battle of Aber-Glein against Arthur map Uther, Pendragon of Brydein, Chieftainess Gyanhumara ("Gyan") nic Hymar is obligated by treaty to marry a Brytoni nobleman. She chooses as her betrothed Urien map Dumarec, son of her clan's worst enemy, in hopes of bringing in lasting peace to her people. Arthur must honor this arrangement, even though he knows that Urien, his arch rival, will gain greater power from it.
When Arthur and Gyan meet, the love that develops between them escalates to legendary proportions. But with her clan's future in her hands, Gyan would forsake her heart's bidding and go through with her obviously ill-fated marriage to Urien. For unless she and Arthur can avert the civil war that is sure to erupt, their love will be doomed to remain unfulfilled -- forever.
