I've enjoyed nearly every Stephen King book I've read, and this is no exception. I liked the main character, and the differentiation of her interior voices was, I think, skilfully done and interesting.

However, there are three stories in this book and one of them doesn't gel. Jessie, trapped in handcuffs, is one. Her past trauma, set during an eclipse in her childhood, is another. Then there's the third: Joubert, the monster in the room. In my opinion, the fact that Jessie briefly thought he was her father is too thin a conceit to hang a story on - it feels like this subplot, which becomes more substantial towards the end of the book, has been tacked on from another piece.

The other events in the book were horrifying enough. They didn't need a third unbalancing the whole when that third didn't fit. One of those cases, I think, where less would have been more.
