Example Input: Welcome Back! . Another great story in the world of Dragonlance!     I was so sad at the end of the War of Souls trilogy, as I thought it meant the end of the world of Krynn for me... I was wrong, and I celebrated the day I found out that Margaret and Tracy were writing prequels.  However, after the Star Wars debacle, I was slightly concerned that this was going to be a "Phantom Menace".   I am glad to say it is not.     This book takes place between Autumn Twilight and Winters Night, and revolves around Riverwind's evacuation of the Slave of Pax Tharkas after the rebellion, and Tanis, Raistlin, Sturm Caramon, Flint, and Tas's search for the Hammer of Kharas - used to make the Dragonlances.  This book focuses largely on Flint, which awesome considering that he played a much diminished role for the majority of the series.  Flint leads the companions in the search and has to deal with the dwarven bureaucracy and xenophobia in Thorbardin.  Compounding the difficulty is an especially clever and ambitious draconian who has fooled the world into thinking Lord Verminard still lives.  I swear, fans of Tas will love this book - as always he has some of the best lines and gets himself into the strangest situations.    My only criticism, [which is not aimed at the authors] and one shared by many reviewers, is the abysmal editing.  There were missing words, spelling errors, type-o's and so forth.  While this does not detract from the well-conceived plot, it does slow the natural flow of the read.  Hopefully the publishers will take an extra week for editing on the next instalment.     Anyhow, this was a great read for fans of the series!    Relic11

Example Input: Disjointed Narrative . I had originally seen this book as a subject of PBS' Frontline several months ago. I was enthralled by the subject matter and decided to get a copy from the local library and read about it myself. What a mistake. The PBS Frontline TV program was so much better than the book. I found Maraniss'  switch from the Viet Nam story to the University of Wisconsin protest story very aggravating; and, as another reader mention, it made for a very disjointed narrative. The juxtapositioning of the two narratives does not work!    I found myself more interested in the war portion of the book than reading about Soglin and his friends embroiled in a protest against Dow Chemical. Frankly, I found this portion of the book to be quite a bore and it almost ruined the book for me. Who cares about college kids and their protesting episodes. It is simply not important.     If you are interested in reading the book, read the Nam portion and skip the protest chapters. Better yet, catch the Frontline episode and skip the book completely.
Example Output: NEG

Example Input: It was perfect for our 3 and 5 year old . My girls loved this book so much we bought it for their cousin.  They have a sweet tooth and really identified with the book. It's very silly. We bought a used version and it was in great shape.
