Theorising Literary Islands is a literary and cultural study of both how and why the trope of the island functions within contemporary popular Robinsonade narratives. It traces the development of Western "islomania" - or our obsession with islands - from its origins in Daniel Defoe's Robinson Crusoe right up to contemporary Robinsonade texts, focusing predominantly on American and European representations of fictionalized Pacific Island topographies in contemporary literature, film, television, and other media. Theorising Literary Islands argues that the ubiquity of island landscapes within the popular imagination belies certain ideological and cultural anxieties, and posits that the emergence of a Western popular culture tradition can largely be traced through the development of the Robinsonade genre, and through early European and American fascination with the Pacific region.
