Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Please Amazon, No Spoilers!

I am not finished reading this book, but I will give it 5 stars anyway. What I object to is browsing through the other reviews given this novel only to find that Amazon.com has included a review from a national publication which reveals the ending of the story, until now unknown to me. The reviewers seem to be able to demonstrate enough tact not to mention too much of the plot; Amazon should be able to do the same. In the future I will be more careful in what I read on this website.
