No, her daughter, Riley, is finishing it. The book is due out October 2024. I don't know how much of it Lisa Marie had finished before she died so I don't know how much Riley has to write. Maybe Lisa left behind notes for the rest of it and Riley is expanding on them? I wish we knew more. Actually, I don't even know if Riley is writing it. Maybe I'm just making an assumption. Maybe the publisher has hired a ghostwriter and Riley is helping them by offering her memories of parts of her Mum's story. Who knows?
So far the only news is the publication month and now this news about the book being reduced from 320 pages to 272 (assuming that's correct info). Not to mention Priscilla is bringing out her own book next year. Yay! /s
This popped up back in January
