While his brothers are given pieces of Scotland, Bhaird, bitter and angry, must cross the sea to Ireland. Oleron decides to come along on the journey.
But as the brothers set sail, the sea churns and takes their ships under... And when they surface, the brothers find themselves in the far future. In the midst of the second World War. "The Riddle Walker" is the second book in Alydia Rackham's thrilling "Weaving of Time" trilogy.
