Few family secrets have the power both to transform lives and to fill in crucial gaps in world history. But then, few families have a mother and a daughter quite like Sala and Ann Kirschner. For nearly fifty years, Sala kept a secret: She had survived five years as a slave in seven different Nazi work camps. Living in America after the war, she kept from her children any hint of her epic, inhuman odyssey. She held on to more than 350 letters, photographs, and a diary without ever mentioning them. Only in 1991, on the eve of heart surgery, did she suddenly present them to Ann and offer to answer any questions her daughter wished to ask. It was a life-changing moment for her scholar, writer, and entrepreneur daughter.
