Example Input: I am using this textbook in a class and it is a whopper. Wonderful pictures, easy to read, clear colors and understandable. I've been working in prisons for 5 years and this book makes a lot of sense. You ought to read their sections on women in prison and on probation. I loved the parts on geriatric prisoners (old cons) and the death penalty. And it is easy to read. More!
Example Output: Positive

Example Input: Mike Connors was in the wrong place at the wrong time and now he is talking to Blue. Blue has something special to share with Mike, Blue is a serial kiler who is stalking the people of the small town where Mike lives. Blue wants to shre his thoughts and feelings with Mike, but Mike doesn't want to know. Mike is also making Blue angry - something that he really doesn't want to do. This gripping book will keep you glued to your seat from the opening scene to the spine tingling twist at the end of the story. An intense read that will leave you thinking long after you have turned the last page and closed the book.
