This is not a book about anything even if it tries to get there. Yes, there is an ethical question raised at one point but it is so quickly rendered moot, that no one really has to wrestle with it… or rather, Klara doesn’t wrestle with it, Josie doesn’t wrestle with it, and the parents who do are so ancillary that the reader doesn’t feel compelled to give it much more thought past “/shudder, yikes!” before moving on.
