The Tactical Crime Division—TCD—is a specialized unit of the FBI.They handle the toughest cases in the most remote locations.

When TCD learns of a school invasion turned lockdown, every agent is ready to engage. With children in jeopardy, the stakes couldn’t be higher. But it becomes personal for hostage negotiator agent Evan Duran when he learns Annalise Taylor is one of the captives holed up with the students in a school for the gifted. He’ll need every resource available at TCD and every ounce of his expertise to turn this disastrous situation into a rescue mission—and if he succeeds, maybe reunite with the woman he never stopped loving.
