No.794
I would not be surprised if she was coerced into releasing it. She has become irrelevant and fragile, so it would have been easy. It also seems suspicious, as you said, that it was written "before" TKAM. About the book itself, I don't think it will be as good. Part of the success of TKAM was that it was really the first popular book to challenge racial problems of the past while said problems were still going on. This new book won't have nearly as much of an advantage in it's release.
