The Vespers still hold Cahill family members hostage, and Vesper One has shown a deadly appetite for killing their relatives. The mission takes Amy and Dan to an ancient city where dangerous secrets wait in every shadow. Their task becomes even more perilous when they discover a Vesper spy has infiltrated the Madrigals, sabotaging their efforts from within.
