This book was part of my studies in MA Sociology of Childhood and Children's Rights, in Institute of Education, University College London. The purpose of this book is to explore the experiences of unaccompanied minors, before and during their migration. Furthermore, it aims to assist the better understanding of these children, hoping that this could help not only the improvement of services offered to them, but also influence people who are negative regarding children's migration. Hence, my research took place in a shelter which is directed by an NGO, in Athens, Greece. In order to do this case study I used qualitative methods, such as group activities and interviews. The participants were boys, between 12 and 18 years old.
