The point of view is a third person style of narration. Yet, it is focused on Bruno's vantage point. This allows Boyne to be able to tell the story of what happens through Bruno's eyes, but also be allowed to freely move into other characters' thoughts and mindsets that allow the reader to understand how unique Bruno is and the state of affairs that surrounds him. The main concept of this style of narration lies in the closing sentence of the narrative:
...nothing like that could ever happen again. Not in this day and age.
This statement holds a level of irony in that the reader would no doubt want to agree with Boyne's statement. Reading it after experiencing what Bruno and Shmuel experience walking hand in hand is a hopeful sentiment with which one can only hope to concur. Yet, in reflecting about the political and personal cruelty that has taken place since the Holocaust, one recognizes that this is regrettably not the case. In order for Boyne to be able to drive home this point, he has to present the story of Bruno in a manner that will allow the reader to understand Bruno's experience, but also allow the reader to accept and ruminate upon the theme that the Holocaust is a unique instant in human history for to deny that it will happen again is as wrong as saying it happen again. In order for Boyne's own point of view to be conveyed, he has to retain this third person narrative with an emphasis to Bruno's own perception throughout the novel.
It is written against the Jewish race a little improvising is in order: perspective on who the author writes the story on. The boy in the striped pyajamas is written in 3rd person. Limited, only showing Bruno personal thoughts and views.
The story is from Bruno's point of view.
