3 stars is about right. I definitely enjoyed the story. There were interesting characters and a terse tight plot. I actually guessed the culprit, but not through the clues, but the psychological trail. All those women were charmed. When Jonesy suspects Eddie but realizes it was a bad choice, I started asking myself if there was someone that fit the bill better and the answer leapt out. The actions afterward solidified my opinion so I wasn't too surprised.

A bit of a deux ex machina to save him, but if you except psychic revelations - as you are asked to from the beginning - being valid, you won't have a problem with the plot.

Not a bad story at all but definitely it was not a horror story, despite the actions of spirits from beyond, so if that's what you are looking for, choose one of his other books. On the other hand, this is a good example of how well King's talents work in other genres. His stories are almost always impressive and you end up caring about the characters.

Note: I don't care if some of the characterizations of the amusement park are inaccurate. It's fiction.
