I understand SM's reluctance to complete the work, but does she honestly believe that once it’s done, no one would buy it? She can’t be that naïve!
Even if she retitled the book to “100 years of Journals” or something along those lines, she could flashback/flash-forward in the book, allowing us to use our imaginations while reading her Edward “views”.
For her just to abandon the Edward approach is ludicrous – since he’s such a feminine draw to the franchise. And dare I say… what about a Jacobs perspective in a book? Perhaps even more insight into his psyche? Some of that raw animalistic unbridled thoughts exposed!
