Does the point or view of the text shift or does it maintain consistent? How can you tell? How does the narration affect our reception?

Most of the POV is from young Maya. Still there is a shift to the older Mays which becomes evident as soon as we see it. Obviously there is a difference between a three year old girl and a mature woman. I think the pairing of these two Mayas, the young and old, gives us a more well rounded perspective about the events that took place. Just think about how you see your childhood now compared to when you were a child.
