Book 1. A Long Day and a Long Night
Ten-year-old Selina Boyce lives in a brownstone in Brooklyn with her Barbadian immigrant family: her mother Silla, father Deighton, and sister Ina. Silla is a strict, no-nonsense woman whose goal is to save enough money to purchase the brownstone they are leasing. Deighton is lackadaisical, impulsive, and he frequently cheats on his wife. His dreams of returning to Barbados and his frivolousness are a source of tension between Silla and him. Deighton inherits a piece of land; Silla wants him to sell it so they can buy the brownstone, but Deighton has fantasies about moving back and building an extravagant house. Suggie Skeete, Miss Mary, and Miss Thompson are a few other characters who appear sporadically; Selina goes to them for companionship and advice.
Book 2. Pastorale
Book 2 opens with a brief description of Deighton and Silla's drawn-out argument over selling the piece of land, and Selina imagining herself as one of the sleeping children who lived in the brownstone before the Boyces. Selina starts to think about womanhood and growing up. She goes to the park with her friend Beryl, where they have an argument about how babies are born: c-section or vaginal birth. Beryl confides to Selina that she has started menstruating. Selina is confused and somewhat repulsed by the idea, as believes it will never happen to her. In reality, Selina feels left out and confused by puberty.
Book 3. The War
World War II is in progress at the start of the third book; this section spans a few years, beginning when Selina is around eleven and ends when she is fifteen. Book 3 is titled "The War" partially in reference to the war, but also in reference to the continuing argument between Silla and Deighton about his piece of land. A group of a few other Bajan women visits Silla in her kitchen while she makes Barbadian cuisine to sell. She vents her frustrations about the land, but she comes with a plan that will get it taken care of. Selina overhears, and Silla threatens to punish her if she tells her father.
Selina searches for someone she can tell about Silla's plans because she wants to protect her father. Deighton, still jobless, begins to devote his time to studying the trumpet. He believes that music will be his next get-rich-quick scheme. Selina tells him about the conversation Silla had with the other Bajan women and her plans to somehow sell the land, but reassures him that it's probably nothing to worry about. She fights with her sister, feeling ignored and unloved. Ina says that no one will ever like her because of her bold and brash personality.
Selina tells Miss Thompson about her fight and her concerns about her mothers plans. Miss Thompson, being a maternal and nurturing person, tries to help by distracting her. She fixes Selina's hair in curls, then Selina heads to her mother's work with the intention of confronting her about her plans to sell the land behind Deighton's back. Silla chastises her for travelling to the part of town by herself at night.
Silla reveals that she has successfully sold Deighton's land for nine hundred dollars. Over the course of a year, Silla forged letters to Deighton's sister and granted his sister the power of attorney to sell the land. Deighton seems to be resigned to this fact, and agrees to take out the money the following day. He is gone the entire day, which raises Silla's suspicions. Deighton comes home with an abundance of frivolous and extravagant gifts. Silla mourns the loss of the money that could have gotten them the brownstone.
The community attends the wedding of ’Gatha Steed’s daughter, which turns out to be an extravagant celebration. Deighton shows up to the reception, but it is clear that everyone know what he’s done, and he is essentially excommunicated. He severely his arm while incorrectly using machinery at a factory job, then begins to follow a cultist religion lead by a man called Father Peace. Deighton he demands to be called "Brother Boyce", and he renounces his family to be with other followers of Father Peace. Silla calls the authorities to have him deported back to Barbados. The family receives news that Deighton either jumped or fell off the ship that was on its way to Barbados, and he drowned.

Miss Thompson reveals to Selina how she got the sore on her leg. It was the result of a racist attack while she was in the South, where a man injured her with a shovel. She also encourages her to attend an Association meeting so she can re-connect with her "people" and her culture a bit more and stop feeling so alienated. Selina begrudgingly agrees to go, but she tells the group they are money-hungry, narrow-minded, etc. and their concerns are petty compared to what they have to face in the white world.
