Irish young adult (YA) literature during the turn of the millennium was slow to confront and address systems of heteronormativity and homonormativity or to propose alternatives for queer belonging and queer futures. Since the legalisation of marriage equality in Ireland in 2015, there has been a notable increase of Irish YA works embracing young LGBTQIA+ characters and queer experiences. Informed by José Esteban Muñoz’s reading of queerness as hopeful and future-oriented, I will examine the evolving representation of queerness in Irish YA fiction over the last three decades and the radical potentiality of contemporary Irish YA fiction for queertopian (re)imaginings.
