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.
I can highly recommend The Adventurers and the City of Secrets. My granddaughter has enjoyed reading all three books in the series, and talks about the characters, Lara, Rufus, Tom and Barney as if she knows them. Gemma Hatt is a very gifted writer.
