Ender’s game - Orson Scott Card

We are all children. They might send us to school. It is required by law. You can't go to school before you're seventeen. They all burst out laughing. They laughed until tears rolled down their faces(They are still a child ,but they have to fight with zerg,even they think Zerg doesn’t inviting human.Reflects the cruelty of society, devoid of humanity. ) It's a science fiction novel that I think must be read, and this book also reflects human nature to a certain extent, and the fact that being a good leader requires giving up kindness.
