Bossy cousin Felicity is left in charge of all the children when Aunt Janet and Uncle Alec go away to celebrate their 15th wedding anniversary, and then Aunt Hetty decides she must go to Charlottetown to protect the farms "water rights". Felicity soon antagonizes the other children into misbehaving. Felix eats ""poison berries"", Sara smears Felicity's cherry pie all over Felicity's dress and even cuts off some of her ""perfect"" hair.

A visit by the Governor's wife makes for confusion as to her identity. By the story's end, the children have all ""learned lessons"" and Sara become friends with the formerly unfriendly Felix and Felicity.

My favourite quote: ""Felicity King is known throughout Avonlea for her cherry pies and sawdust pudding"" ~ Felix King
