I'm not entirely sure what I think about this novella. I had no expectations at all, as the only thing I knew about it, was that it took place during WW2 and that "the boy in the striped pyjamas" was a prisoner of a concentration camp.Generally speaking, I liked the book - although I'm not sure that 'liked' is the right term for the effect it had on me. I liked the way it was written through a young naive boy's POV, even if that boy did at times act FAR beneath his age. I'd have found it a lot more believable if Bruno had been 6 rather than 9. Forgetting the names of some of his best friends after less than a year? Really?Still, it was Bruno's naivete and innocence that made the story work. The ending wouldn't have been at all believable if Bruno had been more mature or world-wise. As it was, it was a tragic story that (apart from Bruno's age) really worked for me.
