Plot Summary

Mary Jane is a quiet, obedient 14-year-old girl who always listens to the advice of her conservative, upper-middle-class parents. Her father is a lawyer, and her mother is a homemaker who obsessively cleans and cooks to project the appearance of managing the perfect home. Both parents care about what the neighbors think above all else. Mary Jane never questioned her parents’ values until she spends the summer of 1975 caring for a five-year-old named Izzy Cone. Izzy’s father is a psychiatrist, and her mother is an aging hippie. The Cone household is in a perpetual state of disarray, but Mary Jane soon develops an affection for the eccentric, spontaneous Cone family.

Shortly after her arrival, Mary Jane learns that rock star Jimmy Bendinger and his TV star wife, Sheba, will be staying at the Cone house for two months so that Jimmy can overcome his drug addiction. Mary Jane soon discovers that the celebrity couple is just as emotionally open as the Cones. After being exposed to their frank conversations about sex and drugs, Mary Jane compares her strait-laced family to the liberated people under the Cone roof.

The teen also develops her talents as a cook during the summer since nobody else in the house seems capable of putting a meal together. During her time with the Cones and their guests, Mary Jane discovers her love of singing and cooking and expresses herself through both with her family’s enthusiastic support. Jimmy finds the strength to overcome his drug dependency and solidifies his relationship with Sheba.

Before the novel's end, Mary Jane’s parents discover that their daughter has been consorting with drug addicts and TV stars, and they are appalled. They refuse to let her associate with the Cones and their guests, with whom she has developed a deep emotional bond. As a testament to Mary Jane’s importance to the Cone household, Jimmy composes a rock song about her that shoots to the top of the pop charts. After Mary Jane makes her mother listen to the song, Mrs. Dillard begins to see her daughter more positively. The girl then manages to forge a friendship between her conservative mother and the liberated Mrs. Cone. By the end of the story, Mary Jane herself develops an appreciation for her abilities and finds the courage to choose her future path in life.
