I haven't heard of a widely - known 'Book Never Ending Story' with a single, well - known author. It could be a self - published work by someone who wanted to create a unique narrative. Maybe it's a local or regional author whose work hasn't gained widespread recognition yet. Without further details, it's impossible to name the author.
I'm not entirely sure as there could be many books with a title like that or it could be a very specific or self - published work. It might be a fantasy story where the plot just keeps on going, perhaps with an infinite number of adventures for the characters.
I don't know if it's a book or a movie. It could be either. If it's a book, it might be a long epic with many chapters that keep the story going on and on. If it's a movie, it could be a series of films that continue the story in a never - ending way.
There's no way to tell just from that name alone. It could be either. If it's a movie, it might be a long - running franchise or a movie with a very complex and ongoing plot. If it's a book, it could be a series of novels with an overarching story that seems to never end. Maybe it has a lot of sequels or spin - offs.
