The Boy in the Striped Pyjamas

"The Boy in the Striped Pyjamas" is a book written by John Boyne. It is a children's historical book, which was published in 2006. The main characters of this book are Bruno, a nine-year-old german boy and his new friend Shmuel, another nine-year-old boy who is jewish.
Bruno lives with his parents and his twelve-year-old sister Gretel in a big house in Berlin. After a visit from Hitler, his father is promoted to Kommandant, and they have to go to live to a place called "Out-With". There, he is really homesick and he doesn't know what to do and he starts exploring the surroundings of the house. One day he meets a boy, Shmuel, behind a fence, and they become friends. This friendship changes Bruno, who wants to know what it is like to live behind the fence.
This book is a really emotive book, which makes you realize how hard it was to live in that situation, and you can find yourself crying while reading the end.
I would recommend this book to everybody, but be aware that it is a sad book. I recommend reading it in original version, because before I read it in English I had read it in Catalan and it is a horrible translation.
