"Pioneer Girl" was one of the first books Ingalls-Wilder wrote, but she could not find a publisher that wanted to print it. "Pioneer Girl" is a nonfiction story of Wilder's life. Her daughter told her to write fictional stories instead. The Little House series is a different from the true story of Ingalls-Wilder's life. She was trying to tell a happy story and to show manifest destiny as a good thing. She wanted the story to make sense, so she left things out if they did not fit her ideas. The fictional books do not talk about when her family moved east to Iowa or her little brother who died young. She also invented fictional characters and made combination characters: Nellie Olson is one person in the fictional books but she was based on more than one person in real life.
