Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Don't use your money for this kind of books

I bought this book because I'm really interested in improving my skill in creating and managing partnerships for my company and I was attracted by the positive reviews on Amazon.Com. Reading the first pages I was unpleasantly surprise by the unbelievable miserable level of this book. I suspect that these reviewers that claim to be CEO and top manager of Fortune 500 companies are just friends and relatives of Sarah. For example, I check the city where of one of these "CEO" is supposed to live and discovered that it doesn't even exist.When you read the book you understand while Sarah needs to push in such unfair way her book (self reviewing). I'm not a CEO but sincerely I recommend everybody to look somewhere else for a good book. This is not a good book at all.
