Becoming a God in the Backrooms

Are There Any Books Written by Minors?

I'd like something like "The Diary of Sima Yan, an Elementary School Student". I really want to read about underage characters. I'm a little bored.

Any Stories Where the Protagonist Turns into an Entity in the Backrooms?

Looking for Pure Backrooms Exploration

Looking for books similar to The Backrooms: I Became a Famous Explorer. No stories about traveling across myriad worlds, please. Those are boring.
