I had the same thought, that maybe I should wait until closer to September to start, but I have to tell you, it's a very "haunting" read. I don't think I'll forget a bit of it, it was just that good!
It's not a book that I would've picked up either, and am so surprised to see how many people have read it already. My sister read it a few months ago and when I brought up to her that I was reading it, she named about five people she knew who were reading it as well. Funny how that happens!
I hope everyone enjoys it as much as I did!
