Zibby Payne can't wait for sixth grade -- finally she and her best friends will rule the school! But on the first day back in class, Zibby gets an awful surprise. Her friends have gone completely girly over the summer, and just want to put on make-up, fix their hair, and talk about boys -- what could be more boring? To save the school year, and show her former best friend Sarah that she doesn't have to follow the crowd to be cool, Zibby decides to become a total tomboy. She dumps her frilly outfits, plays soccer with the boys, and learns to do some awesome new things, like belch out the alphabet. Even if her old friends are giving her dirty looks, Zibby insists she's having the time of her life ... until she tries to form an exclusive "Tomboy Club," and her experiment starts to backfire. Can Zibby find a way to be different and still keep her best friend, or will she end up one lonely, unhappy tomboy? Zibby thinks she has all the answers, in this new, upbeat series for young readers! Tween girls will relate to this feisty sixth grader's trials and tribulations at school and at home, and laugh at the unique way she deals with the constant challenges thrown her way!
