Vince Carver is persona non grata.

As an asset, he's difficult to control. As an operator, he has no equal. Carver may be on the outs with the CIA, but the feds recognize a value proposition when they see one. Sooner or later, his services are always in demand.

He gets a shot at redemption when the son of a Mexican congressman is kidnapped by narcos.

A newly hobbled DEA with diminished operational resources needs two things more than ever: a solution, and deniability. With Delta Force experience in hostage rescue and no official government ties, they tap Carver for the mission in Tijuana.

But the cartels are only half the threat.

Working for a politician has its benefits, but uncovering the root of evil in a powerful family is a killer. Carver must take on gun-wielding narcos, militarized special police, and burrow into the depths of an enduring family rivalry.

If you go out with wolves, they'll teach you to howl.

The Service of Wolves by Matt Sloane is a powerhouse mystery of love and betrayal. From a seedy Tijuana nightclub to the private armies and hidden quarters of Mexico's elite, experience a descent straight to the underbelly of the human condition.
