It's the start of a new term at Miss Cackle's Academy for Witches and Mildred Hubble is determined not to be the worst witch this year. Everything starts so well. Mildred's class has a new form teacher — no more Miss Hardbroom for Mildred and her friends! But then the new teacher, Miss Granite, starts acting fishy; Mildred has a very bad hair day when a hair growth spell goes wrong and she has to put up with know-it-all Ethel Hallow being 'helpful'. To top it all, her beloved cat Tabby is having a nervous breakdown and refuses to fly.

'I think your work will improve no end if you accept my offer of Fenella's cat. And Tabby will have the time of his life down in the kitchen'. Poor Mildred is distraught. On the first day back at Miss Cackle's Academy for Witches her beloved but useless cat, Tabby, is banished to the kitchen. Then the class go for a week by the seaside and Mildred can bear the separation no longer. Stowing Tabby away, she takes him with her. But trying to keep him out of sight of Miss Hardbroom and prying Ethel Hallow leads Mildred from one disaster to another, and soon she really is all at sea. In this long-awaited fourth book about the endearing Worst Witch there's enough excitement to more than satisfy all her many fans.

A new term spells disaster for Mildred! Mildred is determined to lose her embarrassing reputation as the worst witch the Academy has ever seen — but things rapidly get out of hand!
