This second edition of A Critical Introduction to Queer Theory includes new chapters on sexuality and dis/ability; animal sex and species boundaries; queer necropolitics and queer kinship that focus on key contemporary debates, writers, practices and texts. Existing chapters on topics such as race and trans have been substantially updated to include shifts in both theory and practice that have occurred since the publication of the first edition. Key concepts such as identity politics, heteronormativity, homonationalism, materiality and transsomatechnics are discussed at length. This revised edition maintains the original interdisciplinary focus of the first edition and will be relevant to those working in disciplines as diverse as Media Studies, Cultural Studies and Philosophy, Early Childhood Education and Sociobiology.
