Ebner has done some gutsy, thought-provoking research ****
– Sunday Telegraph
Engaging and visceral ... At times, Ebner's undercover work reads like a thriller ... Going Dark pulls back the facade of invulnerability and remorselessness that extremists promote with glossy propaganda, to understand those they recruit.
– Financial Times
Riveting and often deeply disturbing ... Her aim is to expose the way extremist groups manipulate their members in the hope that this will prevent others from being radicalised by them. Her book is a call, too, for policy-makers to rethink their response to extremism ... A punch to the stomach.
– The Sunday Times
Fascinating and important ... Going Dark shows how diverse groups feed off each other, using similar tactics to create social bubbles while exploiting the weakness - or reluctance - of social media firms to control their hate-filled content. It underlines the dangers of ignoring the threat of far-right terror, the normalisation of violence-inciting ideologies and the fearsome power of technology to inspire copycat attacks.
