I liked the part when Cam Jansen figures out the mystery because it is cool and amazing how Cam figures things out with her great memory. I think it is strange that her friend, Eric, was one of the people that got so close to the right number. The illustrator puts a lot of detail in the pictures, so you can look at the pictures and that can give you a clue on what to read. My favorite part in this story is when Cam is trying to guess the right number, because she tries to count them, but many dinosaurs are in front and in the back of other dinosaurs, so it is hard to guess the exact number. I like Cam because she really helps solve the mystery and Cam really thinks about the mystery and not a lot of people have enough patience to do that. In the story, they are at a birthday party and they play games and that remind me of when I go to birthday parties and we also play games. The thing that I wonder about in this book is if Cam actually wants the dinosaurs or if she just wants to win the game. When I read the book, I felt happy because in the end, Cam solves the mystery.
I recommend this book to people that like mysteries and dinosaurs and like guessing games because this book is about that. If you like other Cam Jansen books, then this book is for you. I think 1st graders, 2nd graders, and 3rd graders would like this book because I think this is the right level for them. I also recommend this book to people who like going to birthday parties because in the story they are at a birthday party. If you like books by David A. Adler and illustrations by Susanna Natti, then this book is for you.
