However, there are a few things that could be considered close:
* The original stage script: The script for the stage musical was published and is available for purchase. It contains the dialogue, lyrics, and musical cues for the show.
* The movie script: The screenplay for the film adaptation of Grease was also published. This includes the dialogue and scenes as they appear in the movie.
* Novelisations: There are several novels based on the movie "Grease," although these are not considered canon and are more like fan fiction.
So, while there's no official "Grease" book containing the entire story, you can find the original stage script, the movie script, and various novelisations that offer different perspectives on the musical.
