Mann's ninth book, "Hold Still: A Memoir with Photographs", released May 12, 2015, is a melding of a memoir of her youth, an examination of some major influences of her life, and reflections on how photography shapes one's view of the world. It is augmented with numerous photographs, letters, and other memorabilia. She singles out her "near-feral" childhood and her subsequent introduction to photography at Putney, her relationship to her husband of 40 years and his parent's mysterious death, and her maternal Welsh relative's nostalgia for land morphing into her love for her land in the Shenandoah Valley, as some of her important influences. Gee-Gee, a black woman who was a surrogate parent, who opened Mann's eyes to race relations and exploitation, her relationship with local artist Cy Twombly, and her father's genteel southern legacy and his eventual death are also examined. She ponders the relationship Robert S. Munger, her great-grandfather and southern industrialist, had with his workers. The "New York Times" described it as "an instant classic among Southern memoirs of the last 50 years". An article by Mann adapted from this book appeared with photographs in "The New York Times Magazine" in April 2015. "Hold Still" was a finalist for the 2015 National Book Award.
