For FBI Hostage Rescue Team member Evan Cooper and his partner, dignitary protection duty should have been a piece of cake. Unfortunately, Monica Callahan isnt́ making it easy. Estranged from her diplomat father --- who is involved in a sensitive hostage situation in the Middle East --- she refuses to be intimidated by a related terrorist threat back in the States. That is, until a chilling warning convinces her that the danger is very real --- and escalating. As Coop and his partner do their best to keep her safe, Monica's father triggers an abduction that puts his daughter's life at risk. And with every second that ticks by, Coop knows that the odds of saving the only woman who has ever breached the walls around his heart are dropping. After all, terrorists aren't known for their patience--or their mercy.
