Since an accident left her father unable to work, Jennie Ward has taken on the demanding task of inspecting the isolated seven-mile wooden pipeline that supplies water to Cañon City, Colorado. Despite her responsibilities, Jennie harbors dreams of going back to school and longs for something even simpler: a friend. One day, in a moment of impulsive and seemingly hopeless prayer, she asks God for companionship.

Her prayer is answered almost immediately with the arrival of Leo Day, a paleontology student searching for ancient bones buried along the ridges of the wild Arkansas River. Despite her long workdays, Jennie agrees to guide Leo in his quest.

As Jennie navigates her burgeoning friendship with Leo and her unwavering loyalty to her father, she finds herself torn. Leo, who longs for his own father's approval, could change all Jennie knows. It's undeniable that God has intertwined their paths, but to what end? With so much at stake, what does He truly intend for the preacher's son and the linewalker's daughter to uncover?
