At the close of the twentieth century, J. K. Rowling published what was about to become an integral part of our popular culture and academic discourses. The phenomenal book series soon transformed into a powerful form of social text, as the British writer’s heptalogy undoubtedly contained thought-provoking themes in addition to representations of cultural normalcy. Scholars began to acknowledge that the Harry Potter novels were worthy of serious critical attention especially since their infiltration in the readers’ lives and imaginations gradually, but firmly, reached an international level. Nevertheless, there is still heated academic debate overthe author’s mastery of craft or literary merit and the unprecedented publishing success. Thus, we endeavor to apply a possible-world approach, through which J. K. Rowling’s fictional world in the Harry Potter books gains a valuable angle of exploration. We attempt to assert the aesthetic potential of the narrative, by investigating the internal structure of the textual universe, the development of the plotand the inter-world conflicts.
