Example Input: Not badly written, but ultimately preposterous . Toward the end of this novel, the lead character, Reichs' usual heroine Tempe Brennan, remarks on the "remarkable coincidence" of one of the plot points. By this point in the book, this is like pointing out to a rabid dog that it's got some spittle on its chin.  This book relies on coincidence so fundamentally that if it were removed, it would fall into 3 or 4 different books with little or nothing to do with one another.    Reichs is not a bad writer, and for someone who so clearly comes from a forensic background, is passably adept at character, plot and scene setting. She knows how to build suspense and intrigue, and never lets the technicalities of her lead character's profession -- a forensic anthropologist -- or the intricacies of her work, undermine the story.    This book centres on Brennan's investigation of a religious cult that perpetrates a set of murders. There are lots of interesting points about how cults work, ritual murder and even large group awareness programs get in on the action. And, of course, several forensic investigations where we are treated to the processes of digging up bones, collecting maggots and bugs, and examining various grim bits of the human body.    What undermines this book is that the first half is at least three different, unrelated stories; and the second is such a clumsy and outrageous merging of them into one, that one drifts from disinterest to incredulity. The jacket cover says this book is about the excavation of a 19th century nun's bones, and the mysteries therewith. In fact, this is just story number 1, which is of only tangential importance to the ultimate, main storyline.    It is not obvious, even in terms of the world of Death du Jour, why Reichs needed all this intermingling. It feels like she started writing a travel journal, then stuck a murder into each of her ports of call, then simply declared that they all belong to the same overarching plot. In this context, each individual story feels derivative, and the grand plot feels like a desperate trick.    A well-written and, at times, interesting book, which is ultimately unsatisfying and preposterous
Example Output: NEG

Example Input: Obsolete . This book completely fails to realistically convey the relative risks and profit potential for the average wannabe day trader.  Im talking about someone with less than a few thousand to play the market.  Unless you have big bucks and Level II quotes forget day trading unless you are very lucky. In the trading parlance, I wish I had a short position on this book at its current price, and could cover my short at the current used price! Save your money
Example Output: NEG

Example Input: Helpful and interesting . Having read and reread this book I feel confident in recommending it to anyone interested in learning to deal with with workplace conflict and cohabitation.   The author persuasively and logically argues that most workplace conflict is driven by fears that we may not even be aware of. Using the practical strategies put forth in the book has allowed me to gain greater understanding of where fears come from and how to cope with them. This book would be a valuable tool for anyone interested in turning discord into harmony, both at home and at work.  The final section of the book suffers slightly from what felt to me like a shift in tone and emphasis. This part of the book seemed to be where the author became concerned with sharing his own personal worldview and therefore might be less useful for the hardcore business reader looking for workplace strategies to implement. That being said, I found this portion of the book to be interesting and enlightening to read simply as a human being and not as a "business person".   Highly recommended.
