Two American teenagers catapulted back in time to alter history and save the medieval kingdom of Wales. David and his man-at-arms, Ieuan, find themselves alone and on the run from a company of English soldiers who’ve sworn vengeance for the recent death of their king. Meanwhile, Llywelyn lays on his deathbed from a traitor’s arrow. And once again, it is David and Anna, and all they represent, that holds the key to the survival of Wales.
