What is the author's style in When I Was Puerto Rican by Esmeralda Santiago?

The story is written in first person from Esmeralda's point of view. Esmeralda tells the story of her life, apparently from some of her earliest memories at the age of four. The perspective is written from Esmeralda's memory years after the event. The reader should keep in mind that the story is likely skewed somewhat by Esmeralda's memory over the passage of years. For examples, Esmeralda recalls that having her father's infidelity pointed out by her mother was not enough to matter until the day she realized the truth of the accusations.
