Same for me- I don't want to know too much about the book before hand. I want to be surprised while reading a new book. I used to read all the excerpts that were available for various King books but even that kind of spoiled things so I don't do that anymore.
Imagine my surprise and delight when I opened my Kindle Monday night and there it was! I had totally forgot the release date. But I'm in the middle of The Handmaid's Tale right now and promised myself I'd finish it before jumping into SB. Trying to avoid spoilers is a real trick for us Mods.
I haven't read Sleeping Beauties yet, I'm reading one of the books he wrote with Peter Straub. I thought I heard he is making another book with Straub, but I might be mistaken. I liked Gwendy's Button Box.
