The First Four Years is not considered by many to be in the actual series, as it is written in a much different style than the rest of the books. In fact, this book was not published until after Laura’s death. It was found among her papers in the same orange school tablets she wrote the other manuscripts in. It is unedited by Laura, and is only divided by the four years – three years and a year of Grace. It highlights those first four years after Laura married Almanzo, which includes the birth of Rose, and many of the hardships that continue to plague the life of Laura as a pioneer.
