FBI handler Meg Jennings and her K-9 partner, Hawk, are drawn into a case that involves a fortune in uncut gems, and an enemy whose power and ruthlessness know no bounds . . . Diamonds are no one's best friend when the jewels in question are smuggled conflict gems. Meg Jennings and her Labrador, Hawk, have undertaken many search-and-rescue missions, but this case has an unusual twist.

Agent Finn Pierce of the Organized Crime Program is embedded with the syndicate, but being caught with a wire or tracking device would mean instant execution. If Meg, her partner Brian Foster, and their dogs can track Pierce to a deal location, they can break the smuggling chain while maintaining Pierce's cover. With the syndicate monitoring every move, it's a risky operation with more players than Meg and Brian first assumed-on both sides of the law. And when one of their own gets caught in the line of fire, the team embarks on a desperate rescue mission, knowing that mere seconds are all that separate life and death...
