An aunt is excited by her niece's excitement to be staying in a proper attic, alone with a bunch of books. The aunt goes for her and finds she's traveled to another land "for a holiday," quite literally (literalizing the metaphor of what books do). The aunt is quite pleased although it remains slightly disturbing as well--whisking the child away without expression permission of the child or parents--which adds a dimension of deviousness to the tale.
