Meg Wolitzer presents stories that take the idea of “the magic of fiction” literally—or literarily. The British writer Penelope Lively offers up a tricky combination of love and real estate in “The Third Wife,” performed by real-life husband and wife Patricia Kalember and Daniel Gerroll. The only “trick” in our next story, “Tempo,” by R.O. Kwon, is the trick the mind plays when it wishes the present would restore a lost bit of the past. The reader is Hettienne Park. And Dave Eggers’ “The Alaska of Giants and Gods” includes a real magic act, but also the longing for some other kind of magic, misplaced on a rocky road, to be restored. Kate Burton reads.
