Example Input: No, don't use this.  Really. . I like Eyewitness Guides a lot, particularly for their glossy graphics combined with comprehensive information, but this really doesn't make the cut.  How is it possible to cram Scotland into 224 pages? Well, it is not.  Besides having very poor coverage on Glasgow and particularly Edinburgh, it also has - well, more poor coverage.  Maps for the bigger islands in Northern Scotland are sorely lacking.  More effort has really got to be invested in making this guide before it is worth your money.  I know DK can make some really great guides, so it saddens me that they are now churning out trash like this
Example Output: NEG

Example Input: Connie in NC . I agree with the comment below.  Boring.  I also have read all the books in the series and look forward to each new one.    This one was not up to the standard I expected with the In Death Series.  By the end of the first chapter you knew the killer and why.  The conflict with Mira didn't fit either.  Maybe the next one will be better
Example Output: NEG

Example Input: A True Fire From The Start... . "Shadowfires" was another wonderful book in the long line of great Koontz novels, and this one was no different.    We have the story of a woman named Rachel, and her husband, Eric Leben. Eric was a doctor in genetics who was fighting with his wife until he is pushed in front of a bus, by her, and killed. Rachel felt that maybe freedom was at last hers, until hours later, Eric is missing from the morgue, and we learn the awful truth of his secret work.     I felt that this book had action from the very first few pages, and did not stop until the very last word. I was thrilled with the roller coaster of a ride that Koontz took me on, and i could not put the book down once i started on the journey. Koontz makes great use of location, and our fears of within, to give us this great chiller of the experiments of man to be more than human. A definite gem in the Koontz collection, a must have for any collector, and a great place to start for anyone taking a look at his work for the first time. A Masterpiece. My only wish of this book: It should have been made into a movie. -C
