Everyone's heard of King Arthur, but no one's ever heard the truth. Gwyna is just a girl who is forced to run when her village is attacked and burned to the ground. To her horror, she is discovered in the wood. But it is Myrddin the bard, a traveler and spinner of tales, who has found her. He agrees to protect Gwyna if she will agree to be bound in service to him. Gwyna is frightened but intrigued—and says yes—for this Myrddin serves the young, rough, and powerful Arthur. In the course of their travels, Myrddin transforms Gwyna into the mysterious Lady of the Lake, a boy warrior, and a spy. It is part of a plot to transform Arthur from the leader of a ragtag warband into King Arthur, the greatest hero of all time.
If Gwyna and Myrrdin's trickery is discovered, what will become of Gwyna? Worse, what will become of Arthur? Only the endless battling, the mighty belief of men, and the sheer cunning of one remarkable girl will tell.
