Mary Faith refuses to have an abortion despite strong pressure from family members. She demonstrates a lot of maturity, unselfishness and wisdom for someone her age and in her situation. Her friend Becky Purdue, despite her own problems, is able to provide comfort and support when no one else does.
There is one brief scene early in the story showing Mary Faith and the boy in bed together, but no nudity or sexual activity. Also, it is implied that the relationship between her father and Nell is intimate, but there are no scenes or language showing it directly.
