Little House on the Prairie by Laura Ingalls Wilder, along with the other 8 books in the series, were some of my very favorites when I was young. This picture looks exactly like my copy did (although mine was not in very good shape, having been read over and over by my much younger self).
I was also a great fan of the TV series based on these books starring Melissa Gilbert and Michael Landon.
These stories were of a gentler and perhaps, in some ways, better time. There were still unkind people and still things to be afraid of, but Pa and Ma were always there to take care of the family. My set of books were given away or sold at a yard sale decades ago. I'd like to find another set. I believe I'd still be enchanted. Definitely worth reading, even if you don't have children.
