Query: Good-bye Dr Cook

I have to agree with the majority of the reviewers. It is a real page turner. A page turner in that you keep turning a page hoping the book (and writing) will get better. The book is dull with no real plot development. The characters are shallow. A complete waste of money.After his last book, I told myself I would buy one more of Dr. Cook's books thinking that perhaps that one was an aberration. Sadly, that is not the case. I won't waste any more money on Dr. Cook's books.
