The European Practice EXchange (EPEX) is a small international network of organisations and individual members working in the fields of primary, secondary and tertiary prevention of radicalisation and exit work both within and outside of prison. It aspired to take up the challenge of amplifying, strengthening and connecting practitioners' voices. This publication is the outcome of an intense three-year exchange, as a reply to the following questions: "How can we create a peer-to-peer network for those working in the prevention of radicalisation that offers a space to their (shared) topics and interests? What if, based on this, practitioners wrote a book together?". The document is written as much for other practitioners as it was for those who are curious to hear the voices of professionals with first-hand expertise.
