It's a book with chapters. Basically a regular ass book. When kids are real little, their books are like 15 pages long. Then in like 1st or 2nd grade, they move onto reading big kid books - aka "chapter books" that have enough pages to warrant chapters.

You never hear someone over the age of 7 or 8 mention reading "chapter books" because they're just know as books.

Except anon, who is dumb as fuck.

A book.

it is a book which is long enough that its broken into "chapters" so that you have a good stopping point to pause your reading for the day.

Or in the context of OOP, a book containing many^1^ pages of text and no pictures^2^

1. greater than 30
2. more than 0.5 pages of text per image

Literally just a book that isn't made for children.

It's like a webnovel but not necessarily web.
