Helter Skelter is a very interesting book. Almost every page keeps you on the seat of your chair. It doesn't have a slow moment in it. It has details after details in which you really enjoy. The feeling of it being all real and true kept me reading this book Just think a person like that is still out there, waiting to be released. If that doesn't scare you then I don't know what will. The reality of this book is so increadible that you think it is all made up,but it is all so true. It is certainly a page turner, but I have to warn you, it will scare the hell out of you!
Positive
