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.
OMG!! Real freinds is one of the best books I've ever read! I love the pictures, and the end was nice since it had pictures of the author when she was in school! The only thing I'd recommend is to make Best freinds available for kindle!
