Here's a little story for you. I have a friend that wrote a book. She asked another friend to review it for her. She really wanted an honest review. What she got was a big suprise. It seems after she gave her friend the book to review, her friend got angry with her about something that had nothing to do with teh book. So the friend who was reviewing the book decided to really let her have it. She gave her a one star on Amazon and posted it everywhere else. Prior to that review she had gotten all 5 star reviews. So that was a definate OUCH! I guess there is no way to prevent this other than just be careful not to tick off the people reviewing your book!
