At once heartbreaking and beautifully told, it's a masterwork of nonfiction, a must-read for anyone who wants more of the incredible true story behind Lilac Girls. " --Martha Hall Kelly, New York Times bestselling author of Lilac Girls "Filled with the detailed, comprehensive research Olson is celebrated for, her latest delves into the ingeniousness and fury that drove a band of French female political prisoners to not only survive their time in Ravensbrück, but, once freed, force the rest of the world to take a hard look at the horrors perpetrated by the Germans at a time when so many preferred to 'move on.' A stunning achievement." --Fiona Davis, New York Times bestselling author of The Stolen Queen "Once again, Lynne Olson has retrieved for us a remarkable group of women largely obscured by history.

This book will lift your spirits and restore your faith in the power of human agency." --Kati Marton, New York Times bestselling author of Enemies of the People "Olson combines meticulous research and accessible storytelling with a deep understanding of hope and the urgent need to tell the world . The result is an intricately woven tale of many lives, and a superb account of the French experience in the women's concentration camp at Ravensbrück. Riveting, shocking, and beautiful." --Elizabeth Wein, #1 New York Times bestselling author of Code Name Verity.
