Disappointing really. It's a 700-page book, which was okay until around page 400 or 450 where it really starts to read blandly, almost in Patterson fashion. I finished it, but yearn for the Stephen King olden days.
The subject is clearly outside King's element and although he writes in the credits after the ending about research performed, I am wondering what kind of research went into how tendrils might form from the body and wrap up each sleeping female half of the world population. I'm not saying it should be a reality or real possibility, but just asking the author to describe it in real terms so that I become engaged. At some point I just uttered to myself "cellophane, or whatever". The ending was severely trite. Would be perfect for a film I'd never bother to watch.
