It was excellent because the characters did a lot of interesting things. A girl named Grace is on summer vacation. Four of her friends are not going to camp. Their names are Kester, Maria, Raj and Aimee. They play a lot of games. They make a circus. They play haunted house. They also play safari, space shuttle, doctor and time machine. Grace becomes a detective. They are in the Musical Annie. My favorite character is Grace because I like when Grace thought of a time machine. I think people should read this book because it is interesting.
