This article proposes an analysis of forced displacement and immigration, as well as the sadness and anxiety of exiles in the literary universe of Antonine Maillet. The two novels selected seem at first sight to have little in common, so different are the times and the contexts depicted. They are Pélagie-la-Charrette and Madame Perfecta, both landmark works of Acadian literature, and both portray very particular female destinies. In the first, an extraordinary woman leads her dispersed people from 1755 onwards towards the original Acadia, even if it means crossing borders illegally. In the second, there is a singular encounter between women who have made Montreal their home in contemporary times. Originally from the Acadian coast in New Brunswick and from Spain, respectively, they also show incredible courage even though their movements do not break any laws. That said, the transgressions they commit do reflect realities that mobilize, even in an ambivalent way, postmodern sensibilities. It is then necessary to refer to the comment of Bertrand Westphal according to whom “the postmodern individual cannot project herself into a universe other than that of absolute métissage.” Indeed, each character must deal with otherness when crossing territories and borders where the multiple aspects of diversity create challenges, threats, or feelings of tenderness. It is the awareness of this otherness, of the Other that one refuses, towards whom one also goes and that one is at times forced to become, that will be discussed, in order to grasp some of the meanings of the border in what it can circumscribe or propose as an alternative to the familiar or the intimate.
