Фантастические летающие книги мистера Морриса Лессмора

The idea of books taking flight is so imaginative and charming. I'm curious whether this was inspired by a particular story or just a pure creative choice.

The story really captures that childhood wonder and the magic of discovering stories. Did it remind anyone else of their own favorite books or childhood adventures?

The story has whimsical elements but also touches on themes like loss and hope. I wonder how the author decided where to draw that line for a children's audience.
