On a sweltering day in August 1942, Frankie Washburn returns to his family's rustic Minnesota resort for one last visit before he joins the war as a bombardier, headed for the darkened skies over Europe. Awaiting him at the Pines are those he's about to leave behind: his hovering mother; the distant father to whom he's been a disappointment; the Indian caretaker who's been more of a father to him than his own; and Billy, the childhood friend who over the years has become something much more intimate. But before the homecoming can be celebrated, the search for a German soldier, escaped from the POW camp across the river, explodes in a shocking act of violence, with consequences that will reverberate years into the future for all of them and that will shape how each of them makes sense of their lives.
