Welcome to the world of the Private School Princesses, where our heroine Mim has to do battle with the Car Park Mafia and the Mothers Superior as she drops her children off at the most prestigious school in Melbourne. But in between keeping up with the Joneses - or in this case the Mason-Jacksons - cracks are starting to show in Mim's perfect life as money gets tighter and her husband works ever longer hours. If her two best friends have similar problems, Mim would never know - the Gucci Mamas are far too busy picking their outfits for the races and having manicures to notice each other's troubles. Something's got to give, and it will take a catastrophic, life-changing event to bring Mim to her senses. But will it be too late?
