The exciting saga of Rex and Flavia continues as Bishop Sylvester of Rome sends them on a mission to Emperor Constantine.
The church of Rome seeks permission for a twofold task: to make an official copy of the Scriptures for all the Christians to use, and to build beautiful churches that will reveal the glory of Christ. But mysterious enemies and treacherous churchmen seek to thwart the bishop’s plan. Rex and Flavia find themselves swept up in a great quest, crisscrossing the Roman Empire by land and sea as they struggle to stay true to their purpose and battle the many foes who would seek to do them harm. Yet perhaps their greatest foe is within their own hearts. Can Rex and Flavia learn to bow the knee to the Lord even when His will seems impossible to endure?
