They are strangers at the start, but their lives will become inextricably intertwined, altered in indelible ways. These very different Gold Star Mothers travel to the Meuse-Argonne American Cemetery to say final good-byes to their sons and come together along the way to face the unexpected: a death, a scandal, and a secret revealed.

None of these pilgrims will be as affected as Cora Blake, who has lived almost her entire life in a small fishing village off the coast of Maine, caring for her late sister’s three daughters, hoping to fill the void left by the death of her son, Sammy, who was killed on a scouting mission during the final days of the war. Cora believes she is managing as well as can be expected in the midst of the Depression, but nothing has prepared her for what lies ahead on this unpredictable journey, including an extraordinary encounter with an expatriate American journalist, Griffin Reed, who was wounded in the trenches and hides behind a metal mask, one of hundreds of “tin noses” who became symbols of the war.
