In an ancient city carved from stone, one desperate young woman searches for peace—in the calm before the deadly clash of empires.

 In 106 AD, a single mother can be certain of one thing—destitution. So Cassia and her six-year-old son flee to Petra, her late husband's birth city, in hopes of finding refuge in the loving arms of family.

But the great stone city is not what Cassia imagined. And a secret about her husband reveals her son's true bloodline, making the boy the target of a royal conspiracy.
