Books are like the text you just wrote, we all have ideas that we want to capture and share.
In the world there are different points of view, there are people who have a very particular one, where they can teach you something, even in fantastic stories you can find valuable messages.

I think it all depends on your way of seeing life, if you think there will be something interesting to extract from the book, you will get it, if not, I'm afraid not.

At least that's my way of seeing it.
