This book visits contemporary British children's and young adult (YA) fiction alongside cosmopolitanism, exploring the notion of the nation within the context of globalization, transnationalism and citizenship. By resisting globalization's dehumanizing conflation, cosmopolitanism offers an ethical, humanitarian, and political outlook of convivial planetary community. In its pedagogical responsibility towards readers who will become future citizens, contemporary children's and YA fiction seeks to interrogate and dismantle modes of difference and instead provide aspirational models of empathetic world citizenship. McCulloch discusses texts such as J.K. Rowling's Harry Potter series, Jackie Kay's Strawgirl, Theresa Breslin's Divided City, Gillian Cross's Where I Belong, Kerry Drewery's A Brighter Fear, Saci Lloyd's Momentum, and Julie Bertagna's Exodus trilogy. This book addresses ways in which children's and YA fiction imagines not only the nation but the world beyond, seeking to disrupt binary divisions through a cosmopolitical outlook. The writers discussed envision British society's position and role within a global arena of wide-ranging topical issues, including global conflicts, gender, racial politics, ecology, and climate change. Contemporary children's fiction has matured by depicting characters who face uncertainty just as the world itself experiences an uncertain future of global risks, such as environmental threats and terrorism. The volume will be of significant interest to the fields of children's literature, YA fiction, contemporary fiction, cosmopolitanism, ecofeminism, gender theory, and British and Scottish literature.
