Writer John Boyne explains why he wrote the novel in the form he did:
It goes without saying that a work of fiction set in the time and place of the Holocaust is contentious and any writers who tackle such stories had better be sure of their intentions before they begin. This is perhaps particularly important in the case of a book written for children. For me, a 34-year-old Irish writer, it seemed that the only respectful way to approach the subject was through innocence, with a fable told from the point of view of a rather naive child who couldn’t possibly understand the horrors of what he was caught up in. I believe that this naiveté is as close as someone of my generation can get to the dreadfulness of that period.
