Newbery Medal-winning author Beverly Cleary brings her classic warmth and humor to this story about sibling rivalry and teamwork.

Mitch and Amy both think being twins is fun, but that doesn't stop them from squabbling. Amy is good at reading. Mitch is a math whiz. Amy likes to play pretend. Mitch would rather skateboard. They never want to watch the same television show. And they always try to get the better of each other.

Then the school bully starts picking on Mitch—and on Amy, too. Now the twins have something rotten in common: Alan Hibbler. Can Mitch and Amy set aside their squabbles and band together to defeat a bully?

Second through fourth graders will enjoy reading about Mitch and Amy—and it's especially perfect for siblings and anyone dealing with a bully at school.
