Dinosaurs on the roof

In the town of Belger, Iowa, recently divorced Janet Cawley is attempting to find some peace and quiet, and perhaps a solitary place where she can finally fall apart. She's quit her job teaching fourth grade, though with the money she has, she will probably get along fine for another six months. She still needs to extricate herself from an affair with an ex-colleague that has the neighbors talking, but after that she can spend her time alone, jogging, drinking, and making the occasional trip into town. Her plans are interrupted one morning by the sudden appearance of her now-deceased mother's oldest friend, Bernice, who has an urgent matter to discuss. Bernice's preacher, it seems, has informed his congregation that they are to be visited by the Rapture that very evening -- and Bernice's first question, and most pressing fear, is how her dogs and cats will be fed and cared for after she's gone.
