A prologue is like the beginning of a story, it's like the part of the book that comes before Chapter 1. It's like the first few minutes of a movie before the title comes up.
A prologue is used to give you some important information that you need to know before you start reading the actual story. It's like someone telling you about the background of the story, or a little preview of what's going to happen later on.
Prologues can also help set the tone of the story, like if it's going to be funny or sad, or if it's going to be about adventure or mystery. It's like a trailer for a movie, but instead of showing you clips from the movie, it tells you about it through words.
It's important to read prologues because they help you understand the story better. They give you clues about the characters and the plot. It's like having a secret map to help guide you through the story.
