Images of alienation, melancholy, abjection and death are common to young adult fiction, arguably because they mirror the cultural discourses around adolescence as displaced between two (constructed) ‘knowable’ states: childhood and adulthood. The connection between displacement and melancholy in texts for young adults provides a vast array of narrative symbolism that often blurs reality and fantasy as knowable versus unknowable states respectively. This paper initiates a discussion of the psychoanalytic connotations contained in Sonya Hartnett’s The Ghost Child through the ideas of both Freud and Kristeva. However, in order to question if/how the narrative moves beyond the traditional parameters that construct melancholy as either a clinical pathology or a useful literary/aesthetic device, melancholy is also discussed through the ideas of Gilles Deleuze. The incorporation of Deleuze’s work enables a way to re-think conventional representations of the melancholic as an essentially abject and marginalised subject position.
