In this field-defining book, Schiller casts todays cities as decisive arenas for the making and unmaking of immigrant rights. Bridging disciplines with rare originality, she powerfully shows how local governments and civil society actors shape urban governance through enduring collaboration and irresolvable conflict, opening uncharted avenues for scholars and practitioners alike. -- Raffaele Bazurli, ETH Zürich, Switzerland At a time when migration policies are at the centre of political debate, Maria Schillers book makes a significant contribution to understanding one of the crucial aspects of the issue: the management of diversity and migration phenomena in the relationships between public authorities and civil society actors at the local level. It will be of considerable interest to scholars from various disciplines: migration studies, political science, urban geography, and sociology. It is a book well worth reading for anyone seeking to understand how to better manage migration issues at the local level. -- Maurizio Ambrosini, University of Milan, Italy This book provides a much-needed unsentimental analysis of the positive and negative impact of collaboration in relation to solving high conflict policy problems such as immigration. Based on a compelling theoretical and empirical analysis of how collaboration and conflict are entwined in governance processes, it highlights how collaboration can both trigger and help to sooth conflicts between municipal and civil society actors. Moreover, it points to power-balancing, trust building and/or fostering of shared ideas as crucial for tackling the conflicts that occur along the way. The book is a valuable read for those who are interested in the complexities of collaborative governance in high conflict political settings. -- Eva Sørensen, Roskilde University, Denmark
