This paper is a comparative narratological analysis of two novels – Osmi povjerenik (2013) by Renato Baretić and Brdo (2014) by Ivica Prtenjača – connected by the motif of imaginary islands. The analysis is based on the way Baretić’s Trečić and Prtenjača’s Javorna are represented and the specific meanings the novels attribute to the already mentioned islands. The starting point of the narratological analysis is the study by Marie-Laure Ryan according to which the texts are distinguished at the level of textualization and thematization of space. As regards the textualization, the paper looks at different spatial visualization techniques used by the authors. On the other hand, the thematization aspect concerns specific symbolic meanings attributed to different areas of the two fictional islands. Furthermore, the paper deals with the characterisation of the main characters from the aspect of spatial determinants in which the stories take place. Lastly, the paper discusses the Croatian War of Independence, i.e. the marks it left on the space and the characters, although the stories take place several years after the war ended. In addition to the Croatian War of Independence, the paper deals with the ways the novels are connected with the genre of the utopian novel, considering that an island is a space often associated with utopian meanings.
