This is the first book by Diane Setterfield, but after finishing it I will immediately check out whatever she puts out next. The story starts of slowly, but it quickly builds up momentum until it becomes an unrelenting compulsive read.
Her writing is quite brilliant. There are passages I'm tempted to copy out in this blog post, but really it's far better to discover them in context.
It's hard to get people to read a new author, and even harder to get them to read a book that's hard to classify in a certain genre... is this horror, mystery, crime, psychological drama? Yes, it's kind of all of those. But just ignore my ability to enthuse and check it out!
