This a disappointing book.. No real plot at all. Slow and boring. Was this suppose to be some new twist on a true story? I have read every single novel Mr. Brown has written, however after reading this, it is definitely my last.

Ex Output:
Bad review

Ex Input:
When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.

Ex Output:
Good Review

Ex Input:
I felt like the author wasn't paying much attention as so many recipes start with a large amount of meat and/or eggs in them. This didn't appeal to me at all. Don't waste your money unless you can bring yourself to read every recipe. They sounded good, but they were all just too much.

Bad review
