The lifeguard

In the title story, a teenage lifeguard sees his mystique among the girls on the beach dissolve in a panicked moment when he cannot save a child. In "The Wall," a woman confronts her husband's first marriage, in the form of a mural on a kitchen wall that he is strangely unable to contemplate painting over. In "The Glass-Bottom Boat," a mother on her first trip abroad learns about trust from a solicitous stranger. In "The Snowmaker's Wife," a housewife left alone while her husband works long hours at a mountaintop ski resort starts to suspect his betrayal - as well as her own perceptions.
