Fantasy writing, like literature in general, provides a powerful vehicle for challenging the status quo. Via symbolism, imagery and supernaturalism, fantasy constructs secondary-world narratives that both mirror and critique the political paradigms of our own world. This critical work explores the role of the portal in fantasy, investigating the ways in which magical nexus points and movement between worlds are used to illustrate real-world power dynamics, especially those impacting women and children. Through an examination of high and low fantasy, fairy tales, children's literature, the Gothic, and science fiction, the portal is identified as a living being, place or magical object of profound metaphorical and cultural significance.
