When justice fails, someone else delivers the verdict. FBI Agent Sarah Adams thought she was investigating a routine missing person case. Micah Smith, who escaped conviction for a fatal DUI on a technicality, had vanished without a trace from an Albuquerque parking lot. But Adams' methodical investigation uncovers something far more disturbing: a pattern of disappearances spanning eight years and thirteen victims. All of them guilty of terrible crimes. All of them freed by legal loopholes. Daniel Shepherd is a long-haul trucker with a spotless record and a dark mission. For nearly a decade, he's traveled America's highways dispensing the justice that courtrooms couldn't deliver, targeting those who escaped consequences for rape, murder, and child abuse. His isolated ranch holds the evidence of his work-thirteen chest freezers, each labeled with meticulous precision. When Adams finally tracks down the man the media will call the "Highway Justice Killer," she faces an uncomfortable truth: every person in Shepherd's basement deserved to be there. Now she must grapple with the most dangerous question of her career-what happens when the guilty go free, and someone decides that's unacceptable? Some crimes demand consequences. Some people decide what those consequences are.
