Santoro elucidates notoriously difficult works by the four "mothers of invention" studied - Cixous and Hyvrard from France, and Gagnon and Brossard from Quebec - showing how the rethinking of images associated with femininity and motherhood, a disruptive approach to language, and a subversive relation to novelistic conventions characterize these writers'' search for a writing that will best express women''s desires and dreams. Mothers of Invention situates such ideologically motivated textual practices within the avant-garde tradition, even as it suggests how women''s experimental writings collectively transform our understanding of that tradition. Santoro makes clear the shared ethical and aesthetic commitments that nourished a transatlantic community whose contribution to mainstream literature and cultural productions, including postmodernism, is still being felt today.
