Over the past couple of months, I've realized there's a fifth book to the Seasonal series. I sensed it was there all through the pre-writing and writing of Summer, which was a novel that had to go one of two ways: I mean there was always the possibility, as I was writing it and its resolutions, of a totally other, different, completely liberated 'end' or addition to the sequence, a book that pulled free from the structure and went off on its own tangent. I thought of it, throughout, as the other Summer. Now, I know there's a book, probably called Seasonal, as slim as Autumn. It's a book that breaks the pattern open, simultaneously connected and disconnected to the others. In doing this it makes the sequence true.
