Intrigued by old photos of a woman identified by her grandmother simply as "your grandfather's true love," Sarah Wildman felt compelled to learn the full story of Dr. Valy Scheftel, the lover her grandfather, Karl, had to leave behind when he escaped the Nazi occupation of Austria. Valy's story - revealed in her letters to Karl, Wildman's interviews with Valy's remaining friends and family, and other meticulous research - offers a uniquely fascinating, beautifully tender, and emotionally gripping perspective of Jewish life during the Holocaust. Sarah Wildman. Paperback, 400 pages; 2015 (2014)
