I've read a few of Shaun's books, from the police procedurals of Prosper Snow in The Kult to the wierd and dark worlds in books such as Dead World and Dark Seduction.
But this book is the scariest. It reads as if it's a newspaper report/interview rather than a novel story. The horror in this story is that it is the truth in many towns around the country.
I can't say I "enjoyed" it as such, but it was gripping reading and I didn't want to stop until I found out the ending.
