For me, writing my novels is a conversation with the world. I know that sounds weird. But it means that I “listen” to the world (read the news and commentary, and generally indulge my curiosity), think on what the world has said, and then, respond.
Perhaps it’s different for people who fully plot out their books, but I’m a pantster. No matter how many notes I have to keep me “on track” I go wandering off as I write. The world is talking and it affects how my fictional world develops.
This is why the same book (i.e. one with the same starting point and premise) written again ten years later would be very different.
A few authors have done this.
Robin McKinley wrote Beauty in 1978. In 1997 she wrote Rose Daughter. Both are retellings of Beauty and the Beast. The books are very different. (Beauty is my favorite.)
On a sidenote, I enjoy Beauty and the Beast retellings. I haven’t read the old British romance The Mettlesome Piece by Anne Hepple in years, but I adored it. It’s not quite the traditional Beauty and the Beast in that the Beast rescues himself, and then, rescues Beauty, but it definitely has the theme of being trapped until love finds you.
I even wrote a sweet fairy tale retelling novella myself, Beauty Conquers the Beast.
Sometimes the world is simply telling us to believe in magic.
