I reread this after enjoying Laurie's review -- whose first-time read as an adult made me want to revisit one of my childhood favorites. I still love it, although the classism of the story, as with all of Burnett's books, is grating for modern readers. However, its ultimate message for me is about the wealth to be found in inner development. Sara is a rich girl because she gives generously to others, and a princess because she is master of her own soul. She is not constrained by outer circumstances, but knows how to transform them through her inner attitude and activity. Thus she is free, even when treated like a slave. The images of this 20th century fairy tale are simple and appealing for children, but still ring true to me today.
