An old man and his beautiful daughter live alone in the ancient castle of Caerleon. They are about to be attacked by a horde of brigands led to the castle by a former employee of the old man's. This traitor knows there is a priceless treasure in the castle, but never found out exactly what it was. The daughter seeks out Robin Hood to defend her, her father and the treasure that is beyond price. Robin must ultimately make a staggering choice of loyalty.

Robert de Rainault, high Sheriff of Nottingham, failing one time too many to end the activities of Robin Hood, is dismissed by the king and replaced by Philip Mark, "The Butcher of Lincoln". Mark captures six villagers from Wickham and sends out word that Robin Hood must turn himself in or the captives will die the next noon, and six more the day after that until Robin is captured. Nasir must face the new Sheriff's servant, Sarak, a masked assassin out of the Saracen's past.

After Much is injured in a pit trap, the outlaws seek help for him at the nearest village, Cromm Cruac, a place no one has heard of until now. All is not right, as becomes evident by the things the men see and the way some of them begin to act. Robin must confront Gulnar, a sorceror who once served Owen of Clun.

The Sheriff's young nephew, Martin, is kidnapped by Adam Bell, an ageing outlaw who was the Robin Hood of his day, but now robs only for himself. The Sheriff, using his hostage, Much, as a bargaining chip, persuades Robin to rescue the boy from Bell.
