'This is a terrific book, likely to be widely cited as the best if not the definitive study of Hizbut Tahrir Indonesia (HTI), an Islamist organization recently banned by the Indonesian government. A main strength is the high quality of the interviews, conducted with more than 100 HTI leaders and members, whose confidence the author clearly gained. Balanced and analytical, the book is also theoretically innovative, bringing a new conceptualization of ideology to social movement theory. Not least, its substantive conclusion that HTI is non-violent is persuasive, showing why the recent ban is likely to be counter-productive.'-- Bill Liddle, The Ohio State University, USANawab has captured the inner workings of a global Islamist ideological movement and how it lands in a populous nation like Indonesia. The Hizbut Tahrir is an incubator group for a variety of trends within contemporary Islam and highly relevant to our understand of the intersection of religion and politics. Fascinating details of internal conflict, rivalries and the jockeying for power emerge in this well-researched and deserving book.'-- Ebrahim Moosa, Professor of Islamic Studies, Keough School of Global Affairs, University of Notre Dame, USA'Mohamed Nawab Mohamed Osman wrote a very original and ground-breaking book: he shows how a specific form of Islamist radicalization came to Indonesia from the West; his book illustrates the sudden shift from traditional home-grown Muslim movements, well rooted into the Indonesian culture and society, to a global phenomenon of religious radicalism that finds an appeal among a youth that has lost its connexion to the past.'-- Oliver Roy, European University Institute, Italy
