Part of writing a novel is being willing to leap into the blackness. You have very little idea, really, of what's going to happen. You have a broad sense, maybe, but it's this rash leap. It's like spelunking. You kind of create the right path for yourself. But, boy, are there so many points at which you think, absolutely, I'm going down the wrong hole here. And I can't get back to the right hole. I'm not going to be able to get this section back to the right hole - so I'm just going to have to cut it.
