After fourteen years away, Codi Noline reluctantly returns to her hometown of Grace, Arizona, to attend to her father, Homer. Homer is a practicing physician, but he seems to be losing his memory. Codi has unpleasant and incomplete memories of her life in Grace. She has always felt like an outsider in the town and has been estranged from her father. One of her memories concerns the loss of her mother when Codi was three and her sister Hallie was a baby. She seems to recall seeing a helicopter come too late to rescue her dying mother, even though she was not present at the time. Another unpleasant memory centers on Codi’s pregnancy and miscarriage while she was in high school. She has never told anyone about this incident, not even Loyd, the father of the miscarried child.
Codi has arranged to stay in her high school friend Emelina’s guesthouse instead of with her father. She has been hired to teach biology in her old high school, and she plans to be in Grace for only a year. She is concerned about Hallie, who has gone to Nicaragua to serve as an agricultural adviser in spite of reports about rebels called the Contras who are violently opposing the government there.
Codi reports for her first day of teaching and introduces the students to the skeleton in the biology lab. Later, she takes the class to the river to collect water samples so they can study the river’s organisms under their microscopes, but they discover that there is nothing alive in the water. A local copper-mining company has been trying to extract metals from the mine’s waste and has been releasing water used in the process into the river, causing it to become highly acidic. The poisoned water also affects the orchards in a nearby canyon. Codi files an affidavit about the polluted water at the courthouse because the Environmental Protection Agency has begun to investigate the mine.
In the meantime, Loyd, who is Apache but is also related to the Pueblo and the Navajo, has reconnected with Codi. He now has a job with the railroad. One day, he takes her to the ruins of a Pueblo village that is several hundred years old. He tells Codi he has changed since high school, and he apologizes for his past ill treatment of her.
Homer continues to practice medicine, but he increasingly confuses past and present. He tells Codi that he is taking medicine to slow the memory loss from his Alzheimer’s disease and that he will retire when he is no longer effective. Homer was aware that Codi was pregnant in high school, but he said nothing to her. After her miscarriage, however, when she asked for some aspirin, he gave her something for pain and for cramping. Only in his thoughts does he admit his love for his children.
Codi maintains a correspondence with Hallie,...
