I liked this book. It may have had a lot to do with my having hunkered down and rattled through it - comparatively speaking, at least. If only I can maintain this sort of momentum, I won't need to begin each review with a lament on how much more I'd have got into and enjoyed the book if only it hadn't taken me months to get through it.
Rose Madder is a page-turner with a very real horror executed by a very real villain towards (as we can typically rely with King) well-realised characters. The supernatural element is a bit hit and miss, but not total horseshit. Overall, the book sits on my "good" pile.
I haven't got much else to say about the book. That's not really true. There's a lot more I could say, but it would just be arguing with other people's comments and reactions to the book. I'm not really interested in going down that road.
