Andrew Clements has written an exciting book for middle grade readers based on a unique and original concept. Bobby, the main character, wakes up one morning and discovers he has become invisible. He must keep his condition secret from everyone but his family to avoid being locked up for government experiments, but needs to go out into the world to discover the cause and search for possible cure.
He makes friends with a blind girl who at first doesn’t realize nobody can see Bobby, and the two of them manage to get into some dangerous and exciting situations.
While this book is mainly an adventure story, it involves some Science Fiction, just a touch of romance, and family relationships play an important part as the story unfolds. In my opinion, Things Not Seen should appeal to most young readers because it includes something for nearly everyone.
