Since I'm not familiar with 'the book stories', it could have stories inspired by history. For example, it might rewrite historical events from a different perspective, adding fictional elements to make the story more engaging. It could also have stories about self - discovery, where characters find out who they really are through different experiences in the story.
Well, I'm not sure specifically as I haven't read 'the book stories' yet. But it could have stories about adventures, like a hero's journey through a mysterious land. Maybe it has tales of friendship and how characters overcome difficulties together.
