Review.
I read the review "Shine on" by Margaret Atwood in The New York Times. The first part of the review is the summery of "Doctor Sleep". Then reviewer reasons about Stephen King and his book and I agree with her. Author writes that King is a well-trusted guide to the underworld and his readers follow him through any door. So I do it while I'm reading "Doctor Sleep". Also review says that this novel is about families. I can say so as well because if there were no family links between Abra and Dan, they wouldn't find each other and Dan wouldn't help her. Or if there was no True Knot family, this story wouldn't exist because they were the main evil.
