He meets his match in new wife Sybilla, daughter of his enemy Patrick of Salisbury, as she possesses a strength and courage that equals his own. But when Sybilla's son, William, is seized by the king, John is forced to make a terrible sacrifice. Sometimes keeping your honour means breaking your word . . .
