Query: what a horrible waste of time and money. It is probably the worst book ever written.

I cannot begin to say how dreadful this book is. The person who wrote it should be ashamed and that is why they have neglected to put their name of the book. It claims that people who read this book will die - i would suspect they might die of boredom if they read the whole thing. I only got about half way thru the trash and gave up.
