This is my new favorite Stephen King novel...for now anyway. I love this book. It has been a dream of mine for many years - the idea of this story - what would life be like if that horrible day had never happened? Would it have kept 9/11 from happening? Well obviously = it's much more than a butterfly flapping its wings. But you think the story is gonna be about that and it gets you so wrapped up in so many other strings...and makes you care about all those other strings as much as the title one that you're not sure what you want to happen. Yeah - King's best book ever.
