From the reviews:
"A new report has shed light on the growing threat of terrorist attacks carried out by individuals. ... For the first time, an in-depth analysis is provided of the key features of lone wolf terrorism worldwide over the last four decades. The report provides insights for those working to prevent or minimize the effects of terrorism and political violence, by exploring what drives the lone wolf terrorist to commit mass violence and discussing how this phenomenon can be countered effectively." (Newstrack India, December, 2011)
"Understanding Lone Wolf Terrorism thus comes at a welcome time and succeeds in making this complex phenomenon comprehensible. ... Ramon Spaaij's slim but highly significant account is the first to crunch the numbers on lone-wolf terrorism. ... this necessary first monograph on the study of lone-wolf terrorism, Spaaij helpfully turns to responses: both professionals' and the public's."
