Superb. The book starts with a narrative hook that is devilishly entertaining. What if people couldn't help but admit their worst impulses? It's like this sinful candy, and it keeps the reader coming back for more, waiting to see what the next person will admit. Once you're hooked, then there's context, a coming of age tale that ends with a brutal crime. And then, with the context firmly established... it's time for the Devil to get his due.

Revision: Knocked it down from four to three stars based solely on the movie. The film is absolutely terrible. I felt the same way about the film Annihilation, but the difference with that is that the film Annihilation took very, very little from the book, so I could safely hate the film and still love the book. With the film Horns, yes, there were major differences between it and the book, but there were still significant scenes that were basically untouched. So the film was so bad, it's making me question the quality of the original work.
