William applies to have his father’s title of Earl transferred to him, and discovers a mysterious knight is also a rival for the Earldom. King Stephen, frightened by Jack’s appearance, orders an assassin to kill him. The battle between King Stephen and Maud sees each side’s leader being taken hostage. Philip is tortured into a confession when Waleran tells Maud that he is the man who betrayed Earl Bartholomew.

Waleran and Regan engineer the prisoner exchange so that they remain on the winning side of the war. Tom wants Jack and Alfred to be friends, but their rivalry over their work lives and Aliena is too intense. Meanwhile, William decides to attack Kingsbridge as a way to stop the fleece fair and Aliena’s success. The Hamleighs and Prior Philip are granted rights to Shiring land, but it comes with a price.

Richard returns from war to find his sister penniless, with no more money to support his knighthood. Alfred offers himself to Prior Philip as master-builder. Aliena has to choose between her love for Jack and her oath to her father. Regan forces Waleran to speak to the King about William’s long-delayed Earldom. A disaster at Kingsbridge becomes a way for Waleran to remove Prior Philip from his position.

As a result of his journeys, Jack has learned how to fulfill Tom Builder’s dream of a cathedral filled with light. Aliena tracks Jack by following the trail of his carvings. Waleran offers Philip a new position, but it means that Philip must always obey Waleran. Kingsbridge becomes prosperous again which infuriates Regan and William, who plan an attack that is met with resistance from Richard, Jack and Philip.

Eight years later, Jack’s fixation with the cathedral leaves him little time or energy for anything else, while Aliena’s fixation with the distant Earldom of Shiring has married her to Alfred, a man she hates. Waleran and Alfred develop a plot to get rid of Jack for good and it seems to be working until evidence comes to light that makes all wrongs rectified.
