When Pa Peachey lands a new job, it means a new house in a new part of town for the Peachey family. Everyone's excited about the move - except Betty, who loves her old house and her old friends and her old school.

She doesn't want to live in a new house. She doesn't want to go to a new school. And she definitely does not want to be the new girl.

Nobody seems to care how sad Betty feels except McTavish, the ever-loyal, ever-observant rescue dog. But can even McTavish rescue Betty this time?
