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.
lovely book i recommend it to all young tweens, the best of the three book series in my opinion but i do not recomend that children umder 10should read.this book as it might be too confusuimg for them(unless they are max einstein) :D xb
My 9yo son really enjoyed this book. He enjoys science, and with the main character being female, it helps squish some stereotypes he's exposed to on the daily. I've since purchased the next 2 books for him.
