I mean to read for just a few minutes, to show him I’m not such a prig about math, that I can read a fairy tale as well as anyone else. A few minutes, I said. Just a few. But when I look up hours later, having missed the train, and the final pages resonant in the room with my tears blurring the last lines, I understand my brother. I understand it all. We must, absolutely must, find out where Narnia came from.
