What is the author's style in Rabbit-proof Fence by Doris Pilkington?

In her research and preparation for the book, Pilkington was able to interview some of the principals of the story including her mother, Molly, and Daisy, the youngest of the trio. Pilkington singles out Daisy as contributing much of the information about the trip back. In one incident, the girls are frightened by a "Marbu" in the forest. They reportedly saw the beast and described it as an evil, flesh-eating creature. Undoubtedly, Gracie provided the details of this episode but the reader must keep in mind that this mythical creature was "seen" through the eyes of an eight-year-old. Naturally, there are no doubt other incidents that are shaded by the memory of a very young child about an adventure so many years before.
