the one with the biggest shadow

Daddy-Long-Legs is a novel by American author Jean Webster. The story revolves around an orphan girl named Judy Abbott, who receives a scholarship to Lincoln High School from a stranger, John Smith. She has coined the name "Daddy-Long-Legs" for him because she can't see him and thank him, only his long shadow. Smith's only condition for the scholarship is that Judy write to him once a month, without necessarily expecting a reply.

The story chronicles three years of Judy's life, from her departure from the orphanage to her graduation from high school. The story revolves around the novel's main characters:

Judy Abbott: She is a smart and cheerful girl whose parents died when she was a little girl and she grew up in an orphanage where she developed her talent for writing. One of her articles catches the attention of John Smith (the man with the long legs) and leads to him receiving a scholarship to Lincoln High School where she meets her friends Sally McBride and Julia Bendlett.
