Arthur was once a college professor. Now he just sits at home and eats. He sends out for whatever he needs. But he also pines for a shy former student, Charlene, the closest he has ever come to a love affair. He lost his job because of her, even though she was no longer his student by then and even though they were more friends than lovers. Over the years they have written letters to each other, letters each has treasured and saved and read over and over again.
Arthur finally hears from Charlene for the first time in years. Thinking she might come to visit, he begins to shape up — or at least to get his house in better shape. He hires Yolanda, a pregnant teenager, to clean his house. It turns out that she needs him as much as he needs her.
Meanwhile Charlene has an addiction of her own. She has become an alcoholic, and Kel, her teenage son, cares for her more than she cares for him. Kel is an outstanding high school athlete who thinks he may have a future in professional baseball. His mother's suicide makes this lonely boy even lonelier. He begins the search for his father. Is he the man he has always thought of as his father, the man who abandoned the family years before? Or could it be Arthur Opp?
Without ever bringing Arthur and Kel together, although there is the promise of their meeting when the novel closes, Moore writes poignantly about how much they need each other. Or at least, like Charlene and Yolanda, they need someone.
