The aim of this Master’s thesis is to examine how six fantasy novels reflects or breaks the heteronormativity in society by looking at how gender roles and sexuality are described. The theoretical framework is based on Judith Butler's theory about the heterosexual matrix which requires two separate genders and a compulsory heterosexuality and Yvonne Hirdman's two principles about dichotomy and hierarchy. The method used was idea analysis where dimensions based on the theoretical framework were constructed. These dimensions were: behaviour, tasks, relationships and roles. The result shows that all of the books both breaks and reflects the society's values on gender and sexuality. There are some stereotypes present, for example that intuition is associated with femininity and physical strength with masculinity. However, the books also offer characters of both sexes that break the gender stereotypes, such as strong women and emotional men. This is consistent with what previous research has shown. The relationships offer some examples of norm breaking but the nuclear family and heterosexual couple is a clear norm. Some of the writers seem to have a more conscious approach to norms surrounding gender and sexuality and these books also offer more character variation.
