Just as Simone and Fliss have become friends, Zelda arrives to upset everything. Zelda is loudly, glamorously American, and she's full of ways to improve life at boring school. Soon, quiet, mousy Simone is undergoing a makeover.

And Fliss is about to jeopardise everything to impress a boy. In a new year at school, the girls of Downey House will be breaking all the rules - and not all of them will escape unscathed.
