[The] extrasensory perceptions that Daria has always known she's had develop into a psychic ability to communicate with her long-dead grandmother [in Beyond Another Door]…. Too many themes and personal implications crowd the plot; and Grandmother's appearances, "looking very much like white cheesecloth a trifle damp" and accompanied by silvery angels, push the credibility factor. However, Daria's search for expression through art and her troubled situation with her mother are perceptively drawn, while the subject ensures the book's popularity.
