Colonel Hyrum takes Enders away to a school of battle. Ender encounters a new bully there and fights him too and further humiliates him by spreading rumors.

He later comes to make some friends with some other kids, one of them named Alai. Ender then gets transferred to join the Salamander army, and he has no friends again. His commander does not like him, and this makes it even harder. Ender comes to meet Petra. She teaches him the skill of shooting in zero gravity.

Ender even manages to beat Bonzo, the commander at this game. The commander is furious and attempts on Enders life. Ender beats Bonzo up and later feels bad for it.
Ender and his team become introduced to new simulation and get asked to play and win. As it turns out, the simulation was a real-life war, and Ender was killing buggers believing it was a game. He later comes to know the truth and is sad about it. Valentine offers him a chance to go to another colony with her, and he accepts. Ender discovers a suspicious message from the buggers, which is suspicious because he thought he killed all.
