High-school class reunions, in “The Walk with Elizanne” and “The Road Home,” restore their hero to youth’s commonwealth where, as the narrator of the title story confides, “the self I value is stored, however infrequently I check on its condition.” Exotic locales encountered in the journeys of adulthood include Morocco, Florida, Spain, Italy, and India. The territory of childhood, with its fundamental, formative mysteries, is explored in “The Guardians,” “The Laughter of the Gods,” and “Kinderszenen.” Love’s fumblings among the bourgeoisie yield the tart comedy of “Free,” “Delicate Wives,” “The Apparition,” and “Outage.”In sum, American experience from the Depression to the aftermath of 9/11 finds reflection in these glittering pieces of observation, remembrance, and imagination.
