Warmest regards,



Sometimes you win, and sometimes you die.

On the verge of finding the person who ordered their fathers’ deaths, Special Agents Stella Knox and Hagen Yates are diverted by another murder. A kickboxer whose body is discovered with two bullet holes in his head. Stranger still is a pattern of dead boxers around the state.

Are the murders linked to organized crime? A serial killer? A grudge? Or something more disturbing?

Getting information about the illegal world of underground boxing would be next to impossible without the FBI’s Nashville violent crime unit’s inside connection—Special Agent Chloe Foster, a special agent who lives a secret double life in the ring. But as Chloe works undercover, the deeper she’s sucked into her role.

As the trail of bodies grows, Stella knows they must find the killer, and fast, before Chloe faces the fight of her life...for her life.
