Example Input: Lauren Carr really impressed me with The Last Thing She Said. I loved how she wove characters from previous books and series together, and tied them into a cold case mystery. The humor in this book is laugh out loud. There are plenty of cameo appearances by Gnarly, Sterling, Storm, Thor, Traveler to keep the animal lovers happy. The references to Robin Spencer, Mac Faraday, Archie, the Geezer Squad, Chris Matheson and his family all kept me happy. The book is a gem with so many facets. I loved the mystery of Mercedes Livingston and her husband, the romance, the twists, and of course the canine crime boss!
Example Output: positive

Example Output:
negative
