Zipporah is thirteen when the Spirit descends upon her, opening her eyes to a world beyond the physical goings-on of the villa outside Rome she has always called home. Within hours, she learns what serving the Lord can cost. Forever scarred after a vicious attack, she knows her call is to use this discernment to protect the Way. She knows she must serve the rest of her life at Tutelos, where the growing Roman church has congregated. She knows her lot is set.

Yet is it so wrong to wish that her master, the kind and handsome young Benjamin Visibullis, will eventually see her as something more than a sister in Christ?

Samuel Asinius, adoptive son of a wealthy Roman, has always called Benjamin brother. When their travels take them to Jerusalem for Passover, the last thing he expects is to cross paths with the woman who sold him into slavery as a child the mother he long ago purged from his heart. His sister, Dara, quickly catches Benjamin's eye, but Samuel suspects there is something dark at work.

When Dara, a fortune-teller seeking the will of a shadowy master determined to undermine the Way, comes into the path of Zipporah, a whirlwind descends upon them all.
