Okay kiddo, let me tell you about something called a "chain novel." It's like when you and your friends play a game where each of you adds something to a story little by little.
In a chain novel, a group of writers get together and agree to write a story together, but each writer can only write part of the story. So Writer 1 starts the story by writing the first chapter, and then passes it on to Writer 2. Writer 2 reads Writer 1's chapter and then writes the second chapter, continuing the story. Then, Writer 2 passes the story on to Writer 3, who continues it with the third chapter, and so on.
It's like a big game of storytelling telephone, where each person adds their own ideas and twists to the story. Once everyone has had a turn, the story is complete and is usually published as a book for people to read.
So, a chain novel is a fun way for writers to collaborate and create a story together, one piece at a time like building a puzzle!
