There is newfound freedom from persecution for Christians under the emperor, Constantine, but newfound troubles as well. Errors and pagan ways are creeping into the Church, while many of the most devoted Christians are withdrawing from the world into the desert as hermits and nuns. Quadratus, one of the emperor’s special guards, is concerned over these developments, even in his own family. Then a riot sweeps through the city and Quadratus’ home is ransacked. When he regains consciousness, he finds that his sister, Placidia, is gone. Where is she? And can the Church handle the new freedom, and remain faithful?
