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.
Our 20-month old saw the pictures of this book and "Dunk Skunk" on the dust jacket of "You Can Do Anything Daddy" and would always point them out when we would read YCDAD. So, I purchased both Truck Duck and Dunk Skunk. He LOVES Dunk Skunk, but Truck Duck doesn't capture his attention and finds it boring, despite his affinity towards vehicles and other modes of transport.
