Rye Mallett, a fearless 'freight dog' pilot charged with flying cargo to far-flung locations, is often rough-spoken and soft of regulations.
But he does have a rock-solid reputation: he will fly in the foulest weather, day or night and deliver the goods. So when Rye is asked the 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, worse trouble than bad weather awaits him. He is greeted first by a sabotage attempt that causes him to crash land; and then by Dr Brynn O'Neal, who claims she was sent for the box in Dr Lambert's stead. Rye finds himself irresistibly drawn to the intrigue surrounding his cargo . . . and to the mysterious and alluring Brynn.
Soon Rye and Brynn are in a treacherous forty-eight-house race to deliver the box. With everyone from law enforcement officials to hired thugs hot on their heels, they must learn to trust each other so they can protect their valuable cargo from those who would kill for it.
