Based on extensive reporting across the Middle East, this vital and timely book charts the rise of the most threatening strand of radical Islam to occur in the modern era. It is a totalitarian regime run from the back of pick-up trucks with a propaganda machine built on smart phones. By unpicking the brutal ideology and exterminationist methods against which the West now fights, Andrew Hosken explores how Islamic State could be defeated, not just territorially, but also in the minds of those who support it.
