Query: Fraud in its purest form...

Not only am I incensed at the authors for writing such a terrible book. I would go as far to say that they should be prosecuted for literary fraud and highway robbery. I can forego the money that I spent on this book. But the hours that I pined away at trying to figure out the crap contained in the book is something that I'll never get back. I will never in my life buy another book from Astle, et al. This is the kind of writing that smells of wannabes. Please do not be taken in by these snake oil sellers.
