Annie was an interesting character . She helped slove problems. She's smart and tells Jack things he doesn't know. She is very adventurous because she likes to visit a lot of places.
This book is very funny because it makes me laugh. There are really good characters and there great illustrations. My favorite part was when Jack flew on the pterarodon's back. It was very exciting. Being funny, exciting, and having good characters is a sign of a good book.
I recommend this book to kids who like mystery books. It is one of the best mystery books ever. I think kids of all ages should be able to read this book and learn from it. It's like study cards on the go.
