Mike Grennan is still a target on a cartel kill list—but this time, everyone around him is deemed collateral. And when the threat closes in on his daughter, it’s no longer about justice; it’s about family.
As compromised agencies collide with covert operations designed to erase evidence and people alike, Grennan, his new partner Annie Diamond, and Tony McCollister find themselves trapped on opposite sides of a system that no longer negotiates.
Loyalty becomes liability. Protection becomes exposure. And every decision tightens the spiral toward a reckoning no one fully controls.
When devotion comes due, everyone pays.
