Saturday Girl [EPUB ebook] 

Suzanne thought the bullying was over once Karenna left school three years ago, but when she starts her new job as the Saturday girl in the local hairdressers she discovers that Karenna is the junior stylist – although judging by the way she flounces around the place, anyone would think she was the manager! All the old feelings of dread, terror, and sickness in the pit of her stomach come back and Suzanne realizes that in order to get on with her life she must rid herself of the past . . . and of Karenna.
