"Jessica Stern and J.M. Berger's new book, "ISIS," should be required reading for every politician and policymaker.Their smart, granular analysis is a bracing antidote to both facile dismissals and wild exaggerations.Stern and Berger offer a nuanced and readable account of the ideological and organizational origins of the group." -- Washington Post "By far the most important contribution yet to our understanding of an organization that remains cloaked in mystery and misunderstanding . A brisk, readable, and eye-opening account of ISIS's past, present, and future. This is a book every American should read.

" -- Reza Aslan, author of No God but god and Zealot: The Life and Times of Jesus of Nazareth "A timely and urgent book that is essential reading for analysts and policy makers alike. In what is already a cornerstone contribution, Stern and Berger offer the kind of cold-blood analysis so desperately needed on the poorly understood phenomenon that is the so-called Islamic state." -- John Horgan, author of The Psychology of Terrorism "The first serious book to analyze the rise of ISIS . Stern and Berger write clearly and persuasively and marshal impressive primary research from ISIS's prodigious propaganda to help explain how ISIS became the dominant jihadi group today. It's a terrific and important read." -- Peter Bergen, author of Manhunt: The Ten-Year Search for Bin Laden from 9/11 to Abbottabad "Stern and Berger pull back the curtain to expose facts and myths about the violent Salafi apocalyptic cult calling itself the Islamic State. A must-read." -- Mike Walker, former undersecretary and acting secretary of the United States Army "ISIS emerged in territory occupied by American soldiers, governed by dictatorial regimes, and fought over by sectarian extremists.

Stern and Berger provide context for understanding ISIS's past and considering how its media model may affect future extremist movements." -- Kecia Ali, associate professor religion, Boston University "A penetrating analysis . The book provides important context for an evolving organization and proto-state that is attempting to rewrite the jihadi playbook." -- Aaron Zelin, Washington Institute for Near East Policy " ISIS: The State of Terror is a timely and important history of a movement that now defines the 21st century." -- Sam Kiley, Evening Standard (London) "This book should be required reading for every politician and policymaker." -- Washington Post.
