This thesis focuses on the question: How has the portrayal and evolution of supernatural creatures, specifically fae, in the YA fantasy genre transformed over the past 20+ years, encompassing the decades 2000, 2010 and 2020? Primarily to examine how contemporary novels portray the perception and development of fae in current times within the selected literature and how authors have approached the worldbuilding of fae realms and societies.The examination of modern fae will include chapters on what other academics within the field of supernatural creatures have studied, the base definition of the mythical and folkloric fae, and the literary genre of young adult (YA) fantasy. These definitions open for further exploration of current fae by using these as the context. Hereafter, the following chapters will centre on the fae species and how they are represented, the worldbuilding, which makes the fae’s occurrence realistic within their storyworlds, and the tropes included in most or all of the studied novels. The dataset for this study is the ten novels from the chosen genre spread over the three decades: 2000, 2010 and 2020. Lastly, these chapters will lead to an exploration of the trends modern fae showcase and how these novels reflect the change in the literary world.
