Since 2012, hundreds have left Western countries to join jihadist groups fighting in Syria. Many are still there, many have been killed, but some have chosen to return to their countries of origin. In this remarkable book, journalist David Thomson has gathered their testimonies and analyses with nuance the factors that led to their radicalisation.
