To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
As a therapist I was supremely disappointed with this book. It wasn't a story, but rather statements that are too easily made and dismissed. I would not recommend this book or this author. Far more excellent books on the market.
