In Nero's Rome, Calandra helps her father, a renowned sculptor, complete the most significant commission of his illustrious career. But then a catastrophic fire nearly destroys the imperial city, leaving Calandra reliant on a group of Christians—unusual individuals unlike any she has encountered before. Intrigued by their worship of the Son of an invisible God, Calandra grapples with her mistrust, only to find herself indebted to these believers as they help her rebuild her shattered world. 

 

When Emperor Nero begins constructing his opulent Golden House, the people of Rome grow resentful, suspecting him of starting the fire in order to clear the land for his immense palace. Needing a scapegoat, Nero points at those who follow the Jewish Messiah, forcing Calandra to make an impossible choice between right and wrong, friends and family, love and death.
