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 kids loved reading about the different types of dives into the pool and liked seeing the main character finally get in there and do the cannonball. There is a glossary at the end for the terms used throughout the book that is really helpful. After you read it a few times and start becoming more familiar with it, the book becomes more fun to read together. For me 5 stars would have meant being able to really enjoy it from the very first read and not needing a few rounds to appreciate it fully.
