"I'm thirteen years old, for heaven's sake! I can't afford to act like a child even if you can."
"Those people... well, they're not people at all, Bruno."
Bruno is a curious nine year old who loves to adventure and is curious of his new surroundings at Out-With. During the book, he starts to explore and goes to the fence, and meets a new friend Schmuel. On his last day at Auschwitz, he goes under the fence into the concentration camp, where he later will be exterminated, or killed.
“I certainly am a doctor. Just because a man glances up at the sky at night does not make him an astronomer, you know.”
He put his face to the glass and saw what was out there, and this time when his eyes opened wide and his mouth made the shape of an O, his hands stayed by his sides because something made him feel very cold and unsafe.
Gretel is Bruno's twelve year old sister, commonly referred to as the "Hopeless Case." She commonly flirts with Lieutenant Kotler, who clearly has no interest in her. She is rude to Bruno at all time and thinks that she is smarter than everyone. However, later in the story, she matures and is very depressed about Bruno's disappearance.
The Fury (Adolf Hitler)
"And why should that be important?"
Father is Bruno and Gretel's dad, who holds the position as the Commandant at the age of around his forties. The "Fury" has big things in mind for him, which is why they had to move closer to Out-With (Auschwitz). He is in a very respectful position to his soldiers and is high in the rankings of World War 2.
"Bruno was sure that he had never seen a skinnier or sadder boy in his life but decided that he had better talk to him."
Pavel is Bruno's family's server and sometimes cook. He is a Jewish man who was chosen to serve for Bruno's family. He used to practice as a doctor until the Holocaust occurred. One day, he was so weak that he accidentally spilled wine on Lieutenant Kotler, and we haven't seen him since then.
Adolf Hitler is the commanding general and leader of Germany during the Holocaust. In this time setting of the book, he is 53. He is the reason for all of the deaths of Jewish people, Soviets, and many more. The Fury is the one who made all of the arrangements for Bruno's family to go to Out-With, which is the reason that Bruno dislikes him.
Shmuel is the main character of the book. He is a Jewish boy living in Auschwitz during the Holocaust, and is the exact same age as Bruno. He was originally from Poland, and lived above his father's watch shop. Compared to Bruno, Shmuel is very skinny and unhealthy due to the horrors inside of Auschwitz, where he is usually starved.
