I found "The Lost Prince" on gutenberg.org. I recognized the author's name, but wasn't sure what else she had written. Oh, yeah, "Little Lord Fauntleroy" and "A Little Princess". I may never have read the books, but I saw the movies. :-) Freddie Bartholomew and Shirley Temple.

Oh, and "The Secret Garden" which I'm pretty sure I did read. Countless decades ago. *sighs*
