On a break between missions, Jack Ryan Jr is asked by his mother to visit Sarajevo and track down a girl whose life she saved during the Bosnian War. Finally, he thinks, life might be quietening down.

That's until he meets Aida - grown from a child into a beautiful and selfless woman. Jack finds himself drawn to her, not to mention impressed by her dangerous work helping Syrian refugees enter Europe.

But the region is increasingly unstable, and just as Jack lets his guard down, Aida is violently kidnapped by the Serbian mafia.

With no official status, Jack's pleas for help fall on deaf ears, and he realises he must act alone to save the woman he loves. But as the simmering tensions threaten to bubble over, Jack will soon discover Bosnia is a dangerous place to fly solo . . .
