So the premise of 'The Submission' is that there's an anonymous competition to design a 9/11 memorial and it's won by an American Muslim, an architect born and raised in Virginia, and his name is Mohammad Khan.

Over the centuries, and even today, the Bible and Christian theology have helped justify the Crusades, slavery, violence against gays, and the murder of doctors who perform abortions. The words themselves are latent, inert, harmless - until they aren't.

I read Claire Messud's 'The Emperor's Children,' I read Joseph O'Neill's 'Netherland' - but to me, they're not 9/11 novels. In 'The Emperor's Children,' 9/11 felt to me like a piece of the plot; the novel wasn't wrestling with what 9/11 meant. And 'Netherland' felt the same way. I liked both books a lot but I don't see them as 9/11 novels.

Imagination, it turns out, is a great deal like reporting in your own head. Here is a paradox of fiction-writing. You are crafting something from nothing, which means, in one sense, that none of it is true. Yet in the writing, and perhaps in the reading, some of a character's actions or lines are truer than others.

Sorrow can be a bully.
