Example Input: Gripping story . I found this book at my local used book store.  I was a little hesitant to buy it because I was afraid it would your typical teenage agnst story.  But for only four dollars, what was there to lose?  I was in for a surprise and a real treat!  This book not only captures the teenage insecurities that most of us have felt, or are feeling, but it also captures that nervous, excited, almost panicked feeling a lot of us get after graduating high school, and moving on into the &quot;real&quot; world.  The book was unique in many many ways.  The first third of the book was the main character describing a history of her life by describing pictures she had found, and giving a short story for each one.  The second section, told from her point of view, gave the reader insight into her high school life, dealing with peer pressure, school, and dating.  In the third part of the book,  she begins college, and also begins to spiral out of control, and the books tone shows this.  This section is told in third person, as if she is going through so much, that she feels she is watching herself from the outside. I was very impressed with the writing style and the story line.  I would recommend this book to anyone
Example Output: POS

Example Input: This is a BOARD BOOK - you know the kind with pages thick and durable enough for your toddler to chew . I mention that this is a board book because so many parents seem dissapointed by how few pages it contains.      Your kids will still love it
Example Output: POS

Example Input: a disappointment . I have been greatly been disappointed in this book. I am a total Francophile and soak up just about any book on life in southern France, be it travelogue, novel, cultural study, etc. I have been reading Map of Another Town over the past few months and it's been a struggle. MFK Fisher goes into painfully boring and unnecessary detail on the most insignificant things, like having to go back and forth between offices and buildings while seeking the appropriate vaccinations for a trip to Africa, and what she thinks of every little thing related to the process. She'll devote pages and pages to experiences that have nothing to do with live in Aix-en-Provence and its environs -- it's a map of her own head, where she spends too much time. She finds herself rather fascinating, but I found her self-centered.     I thought it would be interesting to read about life there in the 1950s and 1960s, but again, the book is less a cultural study than autobiographical ramblings (if you can find it, Village in the Vaucluse, a Laurence Wylie cultural study first written in 1957 and updated in 1967 and 1974, is fascinating and was one of my college texts for a French culture course -- 5 stars plus.). I probably will not even bother with A Considerable Town and will finish Map of Another Town only because I feel like I should.    If you are considering this book because life in southern France fascinates you, I would instead recommend any of the Peter Mayle books (not jumping on the bandwagon here; I've read his books from the beginning and own all of them, and his writing style is absolutely delightful and endearing, even when he's being a snob), Yvone Lenard, etc. In fact, Peter Mayle's books so charmingly describe Provence that they serve as a guidebook to the best the region has to offer, so you can visualize and plan your own trip. With his writing style, it feels like you're along for the trip, whereas with MFK Fisher, you wonder when you're going to get there.
