Tom Builder's dream is to build a cathedral, but in the meantime, he must scrounge about to find a lord that will hire him. His search pulls him and his family into the politics of 12th-century England, as different lords vie to gain control of the throne in the wake of the recently deceased king. Prior Phillip, a man raised in the monastery since childhood, also finds himself drafted into the brewing storm as he must protect the interests of a declining church.
