'Despite the near-exponential increase in literature and research on migration/mobility, surprisingly little attention has been paid to the nitty-gritty of the mobility decision-making process. Built around the innovative threshold approach to border-crossing, this book does a wonderful job of illustrating the application of this core concept with a rich variety of case-studies from around the world.' Russell King, University of Sussex, UK ’If you want to understand the mindset, decision-making process and the trajectories of people that migrate read this book! This collection of 19 methodologically solid essays edited by van der Velde and van Naerssen provides many illuminating arguments and illustrations into the mental, locational and trajectory thresholds individuals have to cross to set their journey in motion into the uncertain.’ Emmanuel Brunet-Jailly, University of Victoria, Canada ’This carefully crafted volume of case studies and commentaries on cross-border mobilities, and labour migration in particular, directly addresses the complexity and plurilocal nature of the phenomenon. As the contributors to this book clearly show: mobility is almost always about negotiating borders and, hence, social space. This book is rich with insight and conceptual innovation and is informed by solid empirical evidence. It is a valuable resource - not only for border scholars - and an important addition to the Ashgate Border Regions Series.’ James W. Scott, University of Eastern Finland, Finland
