Example Input: I found this book to be an honest look at the world of hockey goaltending from mites to the pros. My son, who is a youth hockey goalie, enjoyed reading Robb's history and hockey philosophy. A good book for all hockey goalie parents, especially those who are new to the goalie world.
Example Output: Positive

Example Input: This book is about colonel Knox a leader of a freshly starting revolution in America. His mission is to carry around 200 cannons from Ticonderoga back to a city where British forces are docked. The main characters of this book are will Knox 19 year old brother of the colonel, colonel Knox in charge of expedition, J.P. a farmers son .I disliked this book. It drags on and never seems to end. Just when you think your going to get a fight there isn't one .the biggest problem they had on the trip was a river with too thin ice. What's so interesting about that? If I were you I would not buy this book. It is extremely boring.From a reader of this book
