This paper examines representations of societal concern in the futuristic ecological disaster fictions of three British authors: Julie Bertagna (Exodus; Zenith), Jan Mark (Riding Tycho; Voyager) and Marcus Sedgwick (Floodland). The depicted refugee journeys in these futuristic worlds speak into a growing global disquiet that surrounds current historic events. Environmental crises that ground the emergent world orders of depicted future societies set the scene in each coming of age frame: each survival quest embeds social and cultural issues recognisable to contemporary audiences in futuristic representations of changed world orders, limited resources, and isolated communities.17 page(s
