Example Input: This is a book which reads and keeps the reader's attention. It's about how two people who feel an instant attraction discover something wonderful out of their own selfishness. The problem with that is, in real life, we all know some selfishness exists at the same level as most people. One has to take into account how selfish one really is. I also believe everyone wants love regardless where your economic situation is, but it looks like money does not come anywhere near helping out someone in emotional needs.
Example Output: Good Review

Example Input: The book really didn't hold my interest. Not one of Grisham's best books. Hard going at times,and almost nothing on the death penalty. Too many things that did not make sense. Would have been better if he had concentrated on just ONE murder.
