When the daughter of the US Ambassador to Argentina is kidnapped in broad daylight on Christmas Eve, the FBI sends one of its best negotiators to investigate.

Supervisory Special Agent Max Hawthorne arrives at an embassy thrown into chaos as US and local law enforcement hustle to track the young woman. Is this a simple kidnap for ransom, or part of a political agenda? Could it be something more sinister?

Lucy Aston has something to hide. Preferring to stay in the shadows, the lowly, fashion-challenged office assistant resents being assigned to help Max. But Max can’t resist a puzzle…he’s starting to suspect Lucy Aston is not what she seems.

When rumors emerge of a suspected Russian spy operating out of the embassy, Lucy’s carefully constructed life begins to crumble. As she and Max race to rescue the ambassador’s daughter, Lucy has to do whatever it takes to keep her cover from being blown—even if that means betraying the man she’s falling for.
