During his leave of absence from the Roman army, Marcellus discovers a dragon that seems ready to fulfill his dreams of wealth, family, military success, and a secure Empire. But is this alluring beast everything it claims to be? And what about the Christians on his father's estate who show Marcellus a way of life that is both strange and attractive? And why does the dragon view these Christians as a threat to the Empire? As Marcellus tries to answer these questions, he comes to realize that he may have to choose between a life of Roman prosperity and becoming an outlaw in the Empire he loves.
