When Ella's dad refuses to let her have cool school shoes or stay up later than 9:30, Ella decides to take things into her own hands. Being good hasn't got her anywhere, so why not try being bad for a while? It certainly looks a lot more fun and what's a few detentions here and there? But going bad is a slippery slope and soon things are starting to spiral out of control. Can Ella get things back on track? Or is she going to end up with egg on her face? A brilliantly funny new story from Catherine Wilkins, author of the much-loved My Best friend and Other Enemies' series.
