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.
If you write a book about giving a mouse a cookie... chances are that book will sell well. If the book sells well, the publisher will want more books. When the publisher wants more books, the author will write more. When the author writes more, she makes some good books like “Happy Valentine’s Day mouse” which whisks you into a world of Mouses’s friends. You question why cat is so strong and why Fox is so bad at hide and seek. Unfortunately, Happy Birthday Mouse falls flat... it follows the story line of Happy Valentine’s Day mouse except instead of wholesome friendships it focuses more on the gluttony of society. This already learned lesson harkens back to the original story and ends with a predictable and lackluster reference (though predictable, I won’t spoil it). My 1 year old loves the taste of the board book though, so 4 stars.
