Egged on by ringleader Wendy, Jill is right in there with the rest of her fifth grade class persecuting chubby Linda, who is nicknamed Blubber after she gives an oral report on the whale. At last, however, when Wendy, appointing herself judge, puts Blubber on trial for tattling on Jill and her friend (we're never sure it wasn't Wendy who told), Jill defies the bully by insisting that Linda have a defense lawyer — only to find the next day that Linda and Wendy are now best friends and Jill herself the new victim. Actually Jill is teased and ostracized only long enough to learn how it feels to be on the receiving end of grade school cruelty, for her own protest proves the beginning of the end of Wendy's tyranny. Judy Blume presents the scenes of viciousness (the girls forcing a chocolate ant down Linda's throat or making her show the boys her underpants) without commentary and young readers will be appalled long before Jill exhibits any qualms — while enjoying, as usual, those indelicacies like farts and nose picking which only strengthen their general conviction that this author writes directly to them.
