Charlene is one of the smartest girls in the class. Justin is partially deaf and has a radio that picks up signals from his teacher’s microphone. Chip had an accident in a cave and is now invisible. Together they decide to become Invisible Inc., a group of second graders determined to right wrongs using their special abilities.
Because the teacher often forgets to turn his microphone off, Justin overhears a lot of information. When the new ball the school bought just for the second grade is popped, he is shocked to hear the shyest girl in class confessing. He and his friends don’t believe her, and they set out to find who is blackmailing her into admitting to a crime she didn’t commit.
This book is intended for second graders, and barely squeaks into the Chapter Book category.There is a surprising amount of plot for such a short book, but character development is necessarily limited. I liked the inclusion of a kid with a hearing impairment who was mostly accepted as normal by the rest of the class. Having worked previously with a child who had a microphone and radio set, I can attest to the fact that it is easy to forget to turn the microphone off when not talking to the class. Chip’s invisibility seemed a little extreme to me, when the rest of the book was realistic, but I’ll accept it for what it is. Overall a nice solid choice for kids who are just beginning to make the transition from early reader to chapter book.
