Entrenched on his father's farm in southern Idaho's Snake River Valley, Abraham Luchner pulls up roots to join the war effort. Joined by his friend Cameron Terry, an impulsive adventure seeker, Abe determines to sever ties at home in order to minimize distractions. His greatest connection with his beloved canyon and farm is in the form of charcoal sketches he works on each night to escape his present conditions, as well as the letters Cameron reads aloud from his beloved.

Maura Laerty has been claimed as Cameron's betrothed in the eyes of the community. Determined not to become a war widow or caregiver of one more soul who needs her ongoing assistance, she refuses his proposal, at least until he returns. Despite her efforts, Maura soon finds herself saddled with responsibilities that tax her resolve and turn the townspeople away. Her greatest ally comes from a twist of fate as winding and unpredictable as the great Snake River itself.
