Example Input: Berg at her best . Range of Motion was my third Elizabeth Berg novel (Talk Before Sleep and Until the Real Thing Comes Along being the other two) and I must say this is by far my favorite. I loved this book from the opening line to the finishing sentence. Berg portrayed her title character, Lainey, with great sympathy and passion for what she loved. I loved Lainey all the way through the book and she remains my favorite fiction character. Throughout the novel Lainey is dealing with her husband being in a coma after a freak accident along with taking care of her two daughters and helping her neighbor cope with a failing marriage. I cried along with Lainey and smiled at her happy moments the entire time keeping the faith that Lainey's husband would one day wake up along with her. For any fan of Berg or any reader interested in a truly great book, I highly recommend Range of Motion
Example Output: POS

Example Input: vampire Christopher . Christopher Byron's sensibility indicates that he is a small-minded, pathologically envious little weasle of a man, who tries to puff up his empty meaningless life by attempting to denigrate a great woman who has brought great beauty and grace to our culture.  Unless you're one of those nasty-spirited people who find glee in joining the pack of hyenas who hate powerful, brilliant, talented women because the light from great women's souls is too bright and reveals too vividly your pathetic life, avoid this book. Byron is simply a mean little vampire, trying to suck money and notoriety from the life blood of Martha.  Shame on John Wiley &amp; Sons for publishing this book
Example Output: NEG

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
