Throughout the exciting plot line, The setting switches between the serious environment of the Battle School and Ender's changing home: Earth. The story has two main themes: one for each setting since different situations are happening. However, these two themes collide at the resolution.
Andrew 'Ender' Wiggins
Ender Wiggins is the protagonist aka the main character. He is a third-born so he was bullied and picked on a lot on Earth. He is boy of over-genius level intelligence. He has a very unique personality that combines compassion, aggression, and leadership. The theme mainly revolves around his choices and actions.
Valentine is Ender's older sister. She is very caring and loves her family very much, especially Ender. She was rejected from Battle School because she was to caring and wasn't aggressive. She is afraid of Peter so she is often manipulated. However, she can also be manipulative to other people and be very persuasive when needs be. The theme circles around her as well as Ender.
Peter is the older brother of Ender and Valentine. He is very manipulative and persuasive towards other people. He is very mean towards Ender and Valentine because Ender is a Third and Valentine is trying to protect him. He (learns?) that he shouldn't be a bully to Ender.
Petra is Ender's teammate and friend. She is Intelligent (obviously not as much as Ender) and aggressive (obviously not as much as Peter). She is part of Ender's team until Graff interferes.
Alai is a Muslim friend of Ender at battle school that is filled with compassion and intelligence. He shares the word 'Salaam,' a Arabic word meaning peace on to you, with Ender.
Ender's student at Battle School. Ender treats him the same way Graff treated him because Bean and himself were very similar. He trained him the same way he was trained so Bean could grow as a person. Bean ended up as part Dragon Army and Ender's assistant.
The IT think the buggers is planning another attack on Earth.
What does this have to do with Ender?
Ender is the only one who can stop it.
Ender is sent to Battle School right after he nearly killed a bully who picked on him a day earlier.
Ender is desperately trying to defeat the simulator level. His ships twist and turn and avoid laser blasts. Mazer said he would be controlling the simulations. The simulator was random and surprising. Ender, after much time, defeated Mazer.
Ender finds out that the simulation wasn't actually a simulation; he was actually commanding a real fleet of ships in order to destroy the buggers that didn't even attack. The IT attacked with no respect for bugger's kind and the fact bugger's left the humans alone after the Second War. He feels Guilty that killed all of the buggers without even realizing it and set off on a journey to the bugger's planet. He communicated with the Hive Queen promising that he will find a new home planet for Buggers if it was the last thing he did. Ender learned to not believe everything he heard. Peter ends up takin over the world. Valentine learns that if you pretend to someone else you will end up becoming the person you are pretending to be.
Ender sets off into the galaxy with Valentine looking for planets that will save the bugger's from extinction with a small dried out cocoon for the next Hive Queen.
He trains at zero-gravity battling and learns how to be part of the IT. Ender quicker ranks up at Battle School. He ends up killing Bonzo through self defense. He gets assigned to a new army as commander- Dragon Army. After the Dragon Army was known as undefeated, Ender and his friends move to Command School and Ender is put on te simulator.
