Diasporic Marvellous Realism highlights the interesting switch in perspective found in contemporary literary production where the supernatural is regarded from a diasporic perspective as marvellous rather than magical. The titular term is applied to the influence of transterritorialization on the works of first- and second generation immigrant writers when approaching and exploring the myths and legends of their culture of origin. The texts included in this analysis show that the employment of this literary philosophy and narrative technique in contemporary literature involves a fruitful refocusing of the rhetorical gaze regarding the importance of cultural heritage as vindicatory resistance to the lacunae of history and as celebratory re-enfranchisement of diasporic communities in host countries such as Canada and the UK.
