Book excerpt: This book explores the dynamic intersections where cultures, languages and spaces converge, shaping identities and creating new forms of expression. The authors attempt to unravel the complexity of narrative and imaginative spaces by examining cultural identities in global contexts. The essays on literary representations consider abstract border crossings through rewriting and reappropriation in various genres, while also looking at immigrant fiction, post-Anthropocene narratives and hybrid spaces through a postcolonial lens. The essays on history and politics critically examine identity conflicts in the United States, while the contributions on applied linguistics and language pedagogy offer insights into online teaching experiences during COVID-19, sociocultural aspects of language use and the formation of bilingual identities. Employing innovative methods in reinterpreting literary works, political narratives and different types of discourse, past and present, this collection contributes to ongoing scholarly dialogues on the multifaceted challenges associated with identity construction through border crossings.
