how does my book make me think about justice in the world?

My book makes me think about justice in the world because the main character moves around alot. After the lesson in class it made me think like moving around so much she must have seen different living conditions i wonder if that has ever effected her, and if so why isn't it in the book? Also the main character moves around because of the dads job so maybe they always get nice places to live so the areas they live in are never bad. Then i thought about when her mom and dad where together and they owned a resteraunt and how where money conditions then and did it effect her. I don't really think my book shows justice in the book as much as it  brings up questions about justice in the world.
