This book is not very good. I have been listening to the audiobook and, in spite of its short duration, I can't bring myself to finish it. The book is definitely creepy, but I hesitate to call it scary. Simply put, the book is almost entirely devoid of action. I like psychological terror as much as the next guy, but something like the first quarter to third of the book is spent following around the point of view character prior to her arrival at the house. We learn some important details about her personality during this time, but I couldn't help but think you could cut all that chaff out of the book and still be left with the wheat of the story—unfortunately, the wheat is lacking.

The characters spend more time describing in a very empirical and scientific way how they are feeling and reacting to the strangeness of the house than they do actually reacting in any realistic human way. This perhaps fits the premise of the "science experiment" aspect of their staying in the house, but it completely sucks the terror out of every remotely terrifying moment. It reads like a textbook.

Maybe if I were reading this book at 2AM on a moonless Halloween night during a thunderstorm my reaction would be different. It's just not for me.
