A story in a book has its own intentions, even if unknowable to the virgin reader, who just lollops along at her own pace regardless of the author's strategies, and gets where she will. After all, a book can be set aside for weeks, or for good. (Burned in the grate.) Alternatively, a story can be adored for centuries. But it cannot be derailed. A plot, whether abandoned by a reader or pursued rapturously, remains itself, and gets where it is headed even if nobody is looking. It is progressive and inevitable as the seasons. Winter still comes after autumn though you may have died over the summer.
