This is the quote I originally planned to use, from Endless Things:
“. . . For readers, time in a novel goes only one way; the past told of in the turned pages is fixed, and the future, nonexistent till read. But actually the writer, like God, stands outside of time, and can begin his creation at any moment in it. All the past and all the future are present in his conception at once, nothing fixed until all of it’s fixed. Then he keeps this secret from the reader, as God might keep his secret from us: that the world is as though written, and erasable, and rewritable. Not once but more than once; time and again.
” Which isn’t so, of course; which isn’t so. Only in here.” (p 190)
