‘My Naughty Little Sister and Bad Harry + My Naughty Little Sister’s Friends’ is a great book. This book has to stories in one. Each story can be sold separately but also together in this book. The book is written in first person. It is illustrated by Shirley Hughes who is one of the favourite illustrators. My Naughty Little Sister’s Friends is about the naughtiest girl in the world and her friends. Her friends include the Mr and Mrs Cocoa Jones (who live next door), the milkman, and of course Bad Harry. There is double trouble on My Naughty Little Sister and Bad Harry which is about when the little sister and her best friend, Bad Harry, get together and cause havoc. The child’s grandmother’s washday becomes Funday and even a visit to the local library becomes an adventure.
