Iād prefer to not consider this as canon. I prefer Sallyās origin to stay purely Halloween. I think Iāll treat it like old TNBC pc games where Jack had a slime on his hand as a weapon, lol.
The book is indeed cool, interesting plot, feels like tale. I even visualised most of it in TNBC movie style, bc it ~80% felt so. And I like how at the start Sally doesnāt realise her status allows her to actually rule and give orders, not just follow made up obligations. But thatās understandable, considering how invisible she was, being a servant herself all this time.
What I find a little weird is that despite Sallyās actions, emotions, feelings and thoughts being described in details, some other charactersās lines felt flat.
For example, my imagination added more lines into J+S dialogue after Jack has finally woken up. I tried to make myself believe that what is written might be cinematically great. But still I needed more emotional juice there.
Also I wonder whatās Jewelās fate. I have headcanons on her and I donāt want her to disappear from everyoneās life.
