In an ancient city carved from stone, a desperate woman searches for peace.

In AD 106, a single mother can be certain of one thing―destitution.

Cassia flees to Petra with her six-year-old son to seek refuge in the loving arms of family, but discovers the great stone city is not what she imagined.

And family cannot be trusted.

When a secret reveals her son's true bloodline, the boy becomes the target of a royal conspiracy, led by a queen who serves demonic power.

Now in her darkest hour, Cassia encounters followers of The Way, a subversive religious group whose disciples are frequently sentenced to arenas with starved lions and blood-soaked sand.

Will they seek out more danger by helping her?

And what will it take to save her son from the powers of darkness?
