Spain, 974. Gonzalo, a brave but hotheaded knight, unwittingly provokes tragedy at his uncle's wedding to beautiful young noblewoman Doa Lambra: the adored cousin of the bride dead, his teeth scattered across the riverbank. Coveting Gonzalo's family's wealth and power, Doa Lambra then sends Gonzalo's father into enemy territory to be beheaded, unleashing a vengeance that devastates Castile for a generation.
A new hero, Mudarra, rises out of the ashes of Gonzalo's once great family. Raised as a warrior in the opulence of Muslim Crdoba, Mudarra must make a grueling journey and change his religion. Then, he chooses to take his jeweled sword to the throats of his family's betrayers. But only when he strays from the path set for him does he find his true purpose in life.
