Young Julia has everything money can buy—except for acceptance by either Gentiles or Judeans in Tiberias. When she discovers the secret her beloved Greek father has kept all these years, she is devastated. Julia and her Hebrew mother are indeed less than second-class citizens. Her future is dark with clouds of uncertainty.

Jacob, Abigail's brother, is now a young man attempting to find his own place among the community of believers. Does it mean trading away the exhilaration and adventure of his current profession as a caravan guard? Hired by Julia's father to protect a wealthy merchant's caravans on the secretive "Frankincense Trail," Jacob also reluctantly takes on the perilous responsibility of passing letters and messages between communities of believers now dispersed across the land. He is alarmed to discover that Julia, hardly more than a girl, is also a courier. Can their initial mistrust be put aside to accomplish their mission?
