Do you like this book idea?

Iam only 15 and this is just an idea. I want to know is if you think this is a good idea or a bad one!

I know I said "book Idea" but Im not sure If im going to write it or draw it.

My idea is about another universe and no such thing as Earth exists.

In that Universe there is a world where 4 nations are always fighting over different opinions, thoughts and beliefs.

My main character, born in one of those 4 nations, has experienced only pain, until she meets someone that changes her way of seeing things.

*

Thats basically it. I want to show a War between 4 completely different Nations.

I know it sounds really cliche, but there are many flashbacks in my mind where there is this girl and her father telling stories to each other; There is people suffering. But the picture that always comes to my head is people smiling. People are fighting and at war, but some still smile. I dont really have a reason for why they smile, but thats what always comes to my mind.

I wanted to add a bit of fantasy and magic to it and maybe some magical creatures such as dragons.

Just tell me what you think about this! Its only a idea anyways, If im going to use it i have to work on it later..

Thank you for reading!
