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.
My son LOVES the Diary of a Mindcraft Zombie series, so I thought I'd get this series for him to try. He loves them! They are a bit thinner than the zombie books, but the major draw was the fact that the "authors" are the same as the zombie series.
