But a postcard arrives unlike the others, a call for help, Thorn jumps into action, setting off for North Carolina. But before Thorn arrives, he’s intercepted by a federal agent who informs him he’s too late—Flynn had been acting as an informant for the FBI, and when his traitorous acts were discovered, he was summarily executed.The agent proposes a scheme to catch Flynn’s killer using Thorn as bait. Thorn, full of rage, accepts the job if only to get his hands on his son’s killer. The mission takes him to a small town where the gang is holed up, planning an attack on a hog farming operation that has been polluting local rivers and spreading illness through the area.Little by little Thorn discovers that nothing he’s been told is true, and the trap they’re setting isn’t for Flynn’s killer, but for his partner, a woman who proves more daring and dangerous than any Thorn’s ever met. She’s on her own crusade of vengeance, and she and Thorn make an uneasy alliance. With her help Thorn uncovers a conspiracy that stretches far beyond this small Carolina town.
