FBI Special Agent Nathan Burke expected a routine prisoner transport. Instead, he finds an airplane full of corpses and his most wanted terrorism suspect gone without a trace. The investigation plunges him into an international manhunt for Imam Omar Yemeni, a man whose network runs deeper and deadlier than anyone imagined. Meanwhile, Iranian immigrant Leila Kabiri works as a court interpreter, building a new life for her neurodivergent son Darius after fleeing her homeland. But when colleagues start disappearing and foreign operatives make contact, Leila discovers the American justice system itself has been compromised. Someone is watching her every move, and they want something only she can provide. What Nathan doesn't realize is that Yemeni's escape was just the opening move in a much larger plan--one that targets the most vulnerable and threatens mass casualties. As Nathan races across continents tracking his fugitive, Leila finds herself trapped between protecting her family and doing what's right. When their paths finally converge, both will discover that the most dangerous enemies are the ones hiding in plain sight.
