Looking for Books Suitable for Students in the Second and Third Grade of Junior High Schoolᶻz ₍^_ ̫ _^₎

Now that I'm in my second year of junior high school, I'll look for some academic or literature books, which cover all subjects, preferably ones that junior high school students can understand.

Are There Any Books Written by Minors?

I want to read a book similar to "The Diary of Primary School Student Sima Yan". I really want to watch underage, a bit boring.
