In the year 2086, Ender Wiggin lives in a society where aliens have invaded Earth before and are planning to do it again. Ender is currently in the doctors office getting his monitor off. when being taken out the monitor caused ender immense pain forcing the doctors to sedate him.
the kids are making fun of Ender because he lost his monitor. the monitor was used by the government to watch his every move and feel his emotions. they did this to see if the child with the monitor could one day be in battle school to help the effort to fight the buggers. For this reason kids never had a chance to bully Ender because the government is literally watching their every move. the other kids don't have a monitor because the average age to get it off was around three. Ender was six.
After school Stilson and the bullies taunt Ender some more.Soon they physically attack him, but Ender manages to manipulate Stilson into fighting him alone, playing off his pride and taunting, "it takes this many of you to fight one Third?" (Ender is the third child in the family, and Thirds are looked down upon.) When the others back off, Ender kicks Stilson, taking him by surprise, and drops him with the kick. Then, Ender walks up to him and kicks him several more times, making the point that he will win decisively so that no bullies will attack him again--the others will be far too afraid of Ender to try anything. After the fight, Ender sits down and cries until his bus comes, afraid that he is becoming vicious like Peter.
the next day, theres a knock at Enders door. its a mysterious officer. The officer asks Ender about the fight with Stilson, and Ender explains that he did not enjoy hurting Stilson but merely wanted to make sure that he would not be hurt in the future. As he is explaining, he starts to cry and becomes embarrassed. After hearing Ender's explanation the officer stands up, introduces himself as Colonel Graff, director of the Battle School in the Belt, and offers Ender a chance to enter the school. Ender 's first thought was that he didn't want to leave Valentine.
after careful consideration, Ender decides to go and help save the world from the buggers, an evil alien race threatening to take over earth. So Hyrum and Ender leave at once. in the car the Colonel tells Ender that once they leave the driveway, ender can not change his mind. Ender complies and they start off. Just as they were pulling out Valentine comes running out and tells Ender that she loves him forever and will never forget him.
On the ship kids start picking on Ender because the Colonel told everyone just how brilliant Ender is and how much potential he has. The other kids got jealous. one kid kept hitting Ender in the back of the head. Ender caught one of his blows and twisted his arm and threw him, leading to the boy breaking his arm. Later Ender discovers that the Colonel did it on purpose in order to isolate him.
