what is lisa's culture

I'm not sure what context you mean by "culture". Lisa, Starr's mother, is an invaluable source of support and care for her daughter throughout the novel. She encourages Starr to do as much as she is comfortable with in terms of activism and speaking out. Lisa worries for the safety of her family and convinces Maverick that their family should move out of the Garden Heights neighborhood. At the beginning of the book, she works as a nurse in a Garden Heights clinic, but she later secures a higher-paying job in a different hospital which makes the family's move financially feasible.
