What is the author's style in Falling Leaves: The True Story of an Unwanted Chinese Daughter by Adeline Yen Mah?

The story is written in first person from the limited perspective of Adeline Yen Mah. This limitation is actually not a problem because Adeline presents information of her ancestry and tells the story of her childhood from the perspective of adulthood. She includes things she knows though she wasn't there to personally witness all the events she describes. For example, she describes the first meeting of her parents and her own birth. While she can't possibly have witnessed these things, she relates them as they were told to her, probably by her Aunt Baba.
