Why should a novel seek for a tidy closure? Novels are inherently rather messy. They use time very differently from drama. Beginning-middle-end isn’t obligatory. They can wander through a whole lifetime, or follow a great circle like Lord of the Rings, or go right on from what seemed a closure (as happened with Earthsea — my mistake!) I have nothing against endings, but I do write in a form that doesn’t take them too seriously.
