Hanif Qadir is recognised as one of the world's leading specialists in positively transforming violent extremists. He has worked with hundreds of high-risk terrorist and violent extremist cases and has challenged many known figureheads who lead violently extreme groups both at home and abroad. In this essential book for all those who work with young people, Hanif outlines the push and pull factors and the early indicators of radicalisation, and offers decisive and unambiguous advice on how and when to intervene. The book includes anonymous case studies of a wide variety of people Hanif has personally worked with and lays down simple lessons on what success and failure looks like when tackling extremism.
