Rye Mallett, a fearless "freight dog" pilot charged with flying cargo to far-flung locations, is rough-spoken and all business, but soft on regulations when they get in the way of meeting a deadline. But above all, he has a rock-solid reputation: he will fly in the foulest weather, day or night, and deliver the goods safely to their destination. So when Rye is asked to fly into a completely fogbound northern Georgia town and deliver a mysterious black box to a Dr. Lambert, he doesn't ask questions.

As Rye's plane nears the isolated landing strip, more trouble than inclement weather awaits him. Greeted with a sabotage attempt on his plane, he has barely recovered from the crash landing when he meets Dr. Brynn O'Neal, who claims she is receiving the box for Dr. Lambert. Though he has a strict "no-involvement policy" when it comes to others' problems, Rye finds himself being irresistibly drawn in to the intrigue surrounding his cargo . . . and to the mysterious and alluring Brynn.

Soon Rye and Brynn are in a treacherous forty-eight-hour race to deliver the box. With everyone from law enforcement officials to hired guns hot on their heels, they must learn to trust each other to protect their valuable cargo from those who would kill for it.
