Jinx Slater is delighted to have reached the giddy heights of the lower sixth at Stagmount, England's most exclusive school for girls. Her ground floor window affords her an excellent view of Brighton's bright lights, and Jinx is a girl with escape on her mind and a miniature screw driver kit in her tuckbox.
Liberty Latiffe, Jinx's best friend and all round perfect partner in crime, is not at all worried about being caught out by her very strict father. Nor are the rest of the girls.
Until, that is, Stella Fox - Stagmount's newest new girl - arrives on the scene, determined to make her mark.
