The Door in the Wall and Other Stories by H. G. Wells, Science Fiction, Literary

The Door in the Wall: There was something in the very air of it that exhilarated, that gave one a sense of lightness and good happening and well being; there was something in the sight of it that made all its color clean and perfect and subtly luminous. In the instant of coming into it one was exquisitely glad -- as only in rare moments and when one is young and joyful one can be glad in this world. And everything was beautiful there.
