There is no other books that I have read that can relate to this book but since there is no other book I can relate to, I can relate it to a movie called West Side Story which is basically like this book. They both have the same types of stories but in West Side Story there are two lovers that secretly see each other from different sides and in The Boy In The Striped Pajamas, instead of lovers, there are two best friends that see each other all the time. They both have some of the same conflicts such as secretly visiting each other without telling anybody. Another conflict is that both movies have two sides that are enemies. In the book, it war but in the movie it is gang war. They both are really in
common.
