When they were children, Geraint Penderyn and Marged Evans were close friends. But years have passed since then. Geraint is now the Earl of Wyvern and Marged hates him more than any other man on earth. She blames him for her husband’s death, and both she and all the other inhabitants of the Welsh village where she lives blame him for oppressing his people. Geraint has to devise some scheme to convince his people that really he is on their side. A masked savior, a man dressed as a woman named Rebecca, rides out at night to lead his people in rebellion against the toll gates that are destroying them all. He is a daring and commanding figure, and Marged is soon deeply involved with him, though she has never seen his face. Beneath the disguise he is, of course, her friend-turned-foe, Geraint.
