I actually read this book years ago, when I was a teenager. I can't remember all the plot twists and details, but the power of the story has remained with me to this day. Everytime I see it on the shelf, I feel this overpowering sensation that brings me back to the story. This is definitely an intricate mystery. It is at once strange, beautiful, scary, and highly compelling. I found it to be well-written, easy to follow, absorbing, and meaningful. It is one of my favorite fiction books. The story is set in western France, at a chateau. An American family is visiting France and staying at an almost empty chateau, inhabited only by a man and his mysterious daughter. You'll have to read it to find out more!
