“A measured, journalistic approach to a critical topic that affects our society. Henderson explores a variety of extremist groups, their origins, how they recruit, and the ways they communicate…The internet, especially the dark web, is examined for how it is used to spread hostility. The personal stories of those who turned away from their involvement in hate groups are compelling, giving insight into what attracted and then repelled them. Finally, suggestions for how to monitor, respond to, and confront groups and individuals are provided. This valuable narrative is enhanced by photographs and information sidebars. The book is well-sourced, providing an overall look at the topic while pointing to additional resources for more in-depth study.” — Kirkus Reviews
