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.

A collection of gripping testimony from some of the hundreds of jihadists who have returned to France from Syria in recent years. Looks in depth at the motivations and beliefs which pushed them to extremism.
