Merewyn grows up in a savage tenth-century Cornwall - a lonely girl, sustained by stubborn courage and by pride in her descent from the great King Arthur.
Rumon, descendant of Charlemagne and King Alfred, comes from Provence to visit the court of his cousin, King Edgar, and so begins a quest that is to last his whole life, taking him to far places and bringing him sorrow, joy, privation and honour.
Fate in the form of a shipwreck off the Cornish coast brings Rumon and Merewyn together and from that hour their lives are intertwined.
Rumon's search for his lost love, a quest that will lead him across the Atlantic to Greenland, is an unforgettable saga.
