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 analyzes reviews to verify trustworthiness.
my grandmother was sick with lung cancer. she was only expected to live 1 more day. i gave her this book, and i watched her read it. she finished the book with tears in her eyes. she fell asleep quickly. i kissed her on the forehead, expecting her to be dead by morning. the next morning she was walking around normally, and a few hours later, we found out she had gotten over her cancer. my grandmother owes her life to this book. thank you for saving my grandmother.
