Mandy is always getting bullied by Kim, Melanie and Sarah so now she doesn't have a friend in the world. Until a girl that lived next door named Tanya came along and stood up to Kim. Mandy was amazed that someone could stand up to Kim like that so soon they became the best of friends. Every thing was perfect that was when Mandy found that Tanya was a criminal pulling things of the shelf and putting them in her pockets which eventually leads to prison.
I would recommend this book for nine and ten years old.
