The Image Seeker by Amanda Hughes

The Dust Bowl 1936-Battered and near death, Billie Bassett gazes up at the stars from the door of a boxcar wondering if she can go on. Yet, in spite of the violence and privation riding the rails, she endures and becomes one of the finest photojournalists in the nation.
From humble beginnings in an Indian boarding school in Minnesota to high society in New York City, Billie experiences it all. Her pioneering camera work attracts the attention of a group of elite New York journalists who catapult Billie to fame and fortune, but it comes at a price. Her talents are required in the war effort, and she must travel undercover, deep into Nazi Germany as a courier. By her side is the charismatic and acclaimed journalist, Max Rothman, Billie’s harshest critic and dearest friend. But Max does not reveal to her his own clandestine and dangerous agenda.
