"In this important work, Elspeth Guild provides us with a systematic analysis of the relationship between security and migration. Guild brings together critical security studies with a new approach to migration - 'critical migration studies', providing important insights into the changing relationships between citizens and states." Stephen Castles, University of Oxford "Theoretically informed and empirically incisive, Elspeth Guild's account of the sites at which the dynamics of migration meet proliferating claims about security is at once precise and provocative. Its assessment of recent European developments is especially compelling." R. B. J. Walker, University of Victoria
