I like this book because it tells specific details and explains how Chip, one of the detectives, became invisible. I liked when Chip's friend Justin reads peoples lips because he has a hearing problem. I would like to learn to read lips, too!
I recommend this book because you never want to put it down. I think kids in second through third grade would enjoy this mystery. It is fun trying to figure out who did the crime.
