After narrowly escaping arrest, Luciana Betarrini hurtles back to medieval Italy. Once there, she and her brother, Domenico, must decide how far they’ll go to be part of the family, and if they’re willing to risk their lives to hunt down an assassin.
 
Meanwhile, Lady Tiliani Forelli’s family has disappeared in enemy territory. Fearing for their lives—and secretly hoping to cross paths with the Fiorentini she loves—Tiliani goes to Firenze intent on either rescue or seeing justice done. Yet a trap is closing around them all.
 
Together, the Grecos and Betarrinis must find the Forellis’ nemesis and force him to confess to his role in the murders. They assume he has slipped into the serpentine streets of Firenze to evade them. But will they find him in time to save the Forellis?
