The agents of the government's top secret FIA (Final Intervention Agency) do anything from protecting Persons of Interest, to hunting down drug lords, to any other job the government has too many regulations to do themselves. The unorthodox, high-paying division is kept quiet and secretive, just the way director Lawrence H. Dunbar likes it.
Four of his top agents all have pasts that they aren't willing to share, and presents that clash. Carmella Cruz and Rosario Delarosa play a constant, seductive game of cat and mouse, though who is who was never decided, Carmella and Daphne Whittaker worked a job together last year that set them up to hate each other for the indeterminable future, and Daphne and Killian McGratte have never even met, but Daphne already hates him because he might- maybe- be just a little bit better than her.
And Lawrence H. Dunbar is about to send them all on a mission together.
The four, set up in new identities, are taking on the missing cases of many of New York's recently missing elite teens. All of the teens go to the same expensive school, and it's their job to find out why the kids are going missing- and why their parents aren't doing anything about it.
Due to unexpected changes in the very structure of the FIA, the agents are given a two-week deadline that frays all of their nerves. Of course, it doesn't help that Carmella starts falling for a classmate she's been assigned to get information from, Rosario finds himself attracted to a male teacher, and Daphne and Killian keep getting distracted- by each other.
With chapters that alternate between the present and the past, soon enough the people they were and the people they are will get very indistinct- especially when the before and after collide. These agents are in for more than they bargained, and they may very well lose their hearts or even their lives.
