In her new and compelling book, Vanessa Barker explores the Swedish case study to challenge several key paradigms for understanding penal order in the twenty-first century and makes an important contribution to our understanding of punishment and welfare states. She questions the dominance of neoliberalism and political economy as the main explanation for the penalization of others, migrants and foreign nationals, and develops an alternative theoretical framework based on the internal logic of the welfare state and democratic theory about citizenship, incorporation, and difference, paying particular attention to questions of belonging, worthiness, and ethnic and gender hierarchies. Her book develops the concept of penal nationalism as an important form of penal power in the twenty-first century, providing a bridge between border control and punishment studies.
