Autobiographical non-fiction /memoir OR Literary fiction about struggling with multicultural identity (PoC)

As the title says. A mixed race person struggling with culture clash of different sides of families. I am aware of that one book where one sister lives as a white passing person and sister lives as a black person, but that one was two sisters. I'd like to focus on a singular person experiencing both sides. I prefer non-fiction, but am open to literary fiction.
