In this anthropological study Gordana Blagojević, PhD, addresses “the true heroes of our time, the main actors of an extraordinary years-long effort to provide aid, support, protection, and love—Greek men and women who, in the 1990s, opened their hearts and homes to receive children from war-torn areas of the former Yugoslavia, carrying out the entire undertaking while remaining unknown”. In addition to the large number of printed photographs, the book contains the photo and video material available via “QR codes”. “The Invisible heroes of Greece” is a rare anthropological study dedicated to human solidarity, philanthropy and kindness, representing an important contribution to our science, especially in the field of the anthropology of childhood.
