I am currently reading the book The Talking Earth by Jean Craighead George. I think the moral of the story was that you should not always have to believe people. In the book the main character Billie Wind had to obey the medicine man Charlie Wind who is also her uncle. When Billie's sister said that Billie did not believe In serpents he sent her off to see them.
I think this because in the story she has to go off because Charlie wants her to see the serpents. When Billie sees the serpents she does not no how to get back.
