This is book three in the TJ and the Time Stumblers series. I think this series has great appeal for kids because of the silly dialogue, malfunctioning machines, and general chaos. In the midst of all the catastrophes, Myers manages to convey a different message in each book. In this book, the message is to say nice things about others. TJ learns that it is easier to say only nice things about others by only thinking nice things about others. This stems from viewing others as a unique and special creation of God.
I recommend this series of books to kids and adults who have kids. It is light-hearted and funny with a valuable message!
