I analyze the way in which the Bildungsroman seizes on bisexuality in two contemporary French novels: Saccage (2006) by Éric Jourdan and A Boy Like Another (2012) by Joël Breurec. A novelistic genre representing the entry into adulthood of a young protagonist and his identity construction, the Bildungsroman proves here to be an adequate analytical tool for understanding the construction of bisexual identity through literary strategies aimed at represent it.
