This is yet another great book by Judy Blume. It all starts when a plump girl called Linda reads her project on the whale. Her class esp. Jill takes great fun in teasing her and calling her 'Blubber' but the tables soon turn when Jill is teased by the class and is called 'Baby Brenner' by her best fiend. This is a must read if your ever thinking about hurting someones feelings or calling them names.It shows the consequences and how you can be a bully without even knowing it. This book is a short easy read it is probably aimed between the ages of 8-11. I am 12 though and have read it many times.
