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. A Philadelphia syndicate is importing diamonds from war-torn African nations and selling them with fake certificates to Stateside dealers. 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...
