Claudia Carli's friendship with Alie Lopes Dias's sister Gretha and discovery of Alie's friendship album set her on a decade-long mission to trace the girls' lives and preserve their memories. Her book is as faithful as it can be to every detail she learned from Gretha and the few women who have survived. She is currently a project leader for the educational project War In My Neighbourhood, which brings elderly and children together around stories from WW2. She lives in Amsterdam.
