The White in the Wind. Blood Relations

Foreign intelligence services seek to influence events and outcomes when opportunities arise in other countries. In a bitterly divided U. S. political spectrum, Russia's intelligence services make use of social media to create the illusion of an extensive, powerful left-wing movement known as Antifa. In this installment of the Blood Relations Series, the Russian Federation funds rightwing militia groups to kidnap three Republican governors from midwestern swing states.
This kidnapping is allegedly claimed by Antifa which conducts a trial accusing their captives of capitalistic crimes against the citizenry. The governors are sentenced to death. In The White in the Wind, the CIA discovers the Russian GRU role in this charade, but they can neither action on their own nor can they share the information with U. S. law enforcement agencies without compromising sources and methods.
Instead, the CIA arranges to have one of its foreign undercover agents, who operates without official recognition abroad, to be discredited and deported back to the U. S. where he takes up residence in Whitefish, Montana. With his old identity restored, he appears to be a person a questionable gap in his history that frustrates the local law enforcement official. The local militia group wields an outsized influence in this small western town.
It's only a matter of time before they are in conflict with the Carrullo family who are then drawn into the kidnapping and trial. The resulting struggle is what you'd expect when small town xenophobia collides with the sophisticated assassins in the Carrullo family and their blood relations.
