Title: Bedtime stories in OR
Review: Do you like key risk indicators? A good one for 'book purchase' is to see the number of people reselling it, trying to cover the loss of buying a bad book or a book they do not need anymore. In this particular case, this book was released like two months ago and the number of people already reselling it in the secondary market is very high. For example, today 6 readers are selling this book. I believe this tells more than anything else. Buy at your own risk!
