This is a fun and interesting book. I think it is good to read for all ages because they are on a very weird mystery that is not found in a lot of mystery books. Nancy and Bree are on the case to see who stole their teacher's marble.

Ivy and Bean join a dance class. They thought it would be easy at first. When they get a role that they do not like, they try to get sick. The story is very interesting.

This is a really good book.There is a lot of details and I suggest you read this book at least 1 time. I can picture the story in my head when there is no picture. It gets very interesting when you read the middle of the book. The other parts are good too but the middle is the best because it is funny.
