I just finished an excellent book, Mary Coin. This work of fiction by Marisa Silver is based on the subject of the famous Migrant Mother photograph from the Depression by Dorthea Lange.
The story weaves together the lives of these two women - Mary Coin based on the life of Florence Owens Thompson and Vera Dare based on the life of Lange. You also meet Walker and his significance is revealed as the story unfolds.
The book was heartbreaking at times and rich with beautiful language. It was a story of love, loss, art, hard times, family, and finding answers.
