Very often, we would classify a book about young kids growing up as a “coming-of-age” story. And very often that sort of story would have the characters asking questions about their identity – that is, as they grow up, they’d ask themselves, “Who am I?” (Not in an amnesia way, but in a “They say I’m just a kid, but who am I really?” sort of way.) Now, we don’t think Ender’s Game is really a coming-of-age story. For one thing, people usually change in a coming-of-age story, but the Ender at the beginning (who breaks the unwritten rules of combat and kicks Stilson to death) is not all that different from the Ender at the end (who breaks the unwritten rules of war and destroys the bugger homeworld). So when we say that Ender’s Game has a theme of identity, we mean it has a very particular set of questions. It’s not so much “Who am I?” In Ender’s Game, the identity question is “Am I a vicious killer like Peter?”
