This book is the first comprehensive look at the defeat of ISIS and the future reshaping of the Middle East. Based on four years of on-the-ground reporting, research in ten countries in the Middle East, a thousand hours of interviews with key players and access to generals, spies, policymakers, soldiers and refugees, After ISIS provides a unique window into the battle for the heart and soul of the Muslim world, portraying why we need to be informed about changes on the ground after the defeat of ISIS. Understanding these events and the choices ahead will determine if ISIS and similar ideologies will reemerge, if a new war will take its place, or if a younger generation of leaders will create a new Middle East. As ISIS recedes, the decisions made in the region and in Washington matter more than ever.
