Fourteen-year-old Frankie Ward is used to being the new girl at school, but even she is unprepared for life at St Mark's College. Finding herself isolated from the rest of the girls, Frankie is drawn to flamboyant and dramatic Suzy, who captivates her with stories of 'The Blue Lady' - the ghost of an ex-St Mark's pupil who died in mysterious and tragic circumstances. One night Suzy persuades Frankie to help her contact The Blue Lady via an Ouija Board - and the girls unleash a terrifying spirit who seems set on destroying not only their friendship but Suzy's sanity. Determined to rescue her friend, Frankie enlists the help of Seb, a mysterious and alluring boy from sister-school St Hilda's. Seb is as interested in St Mark's past as Frankie - but does he have as many dark secrets as the school?
