School life has never been so splendid as in these brand-new editions of the classic Blyton series, "St Clare's". The O'Sullivan twins are head girls! And two heads are better than one, with the new girls they have to sort out...There's two cheeky first formers - more twins! - and a sulky new girl in the sixth form, Morag. Morag detests St Clare's. She's only happy when she can escape to the local riding stables. The twins are sad it's their last year at St Clare's. Before they leave, will they find out what's wrong with Morag?
