Except for the first chapter, it is written in letters to Daddy-Long-Legs from Judy, an orphan sent to college on scholarship. The only thing the giver of the scholarship wants are letters once a month. He wants to educate young Judy as an author and insists letters are the best way to promote writing. It is a wonderful story of romance, growth, and friendship.
If I was stuck on a desert island and had to choose one book to have, I'd most likely choose this one. I'd also hope I had a ream of paper to scribble on. Judy's letters inspire. In both of my editions of this book, there are excerpts of Jean Webster's life. I find those pieces of history as fascinating as the fictionalized accounts of Judy in college.
Fred Astaire was in a horrible film version of this novel. It was a good movie, but was terrible if you loved the book and anticipated something similar. So, don't watch the movie, read the book!
