Fourteen-year-old Mia Thermopolis is still struggling to come to terms with the fact that she's a princess - and heir to the throne of Genovia! But when she announces on national TV that her mum is pregnant by her algebra teacher and plans to marry him, a right-royal fuss results! Because now Mia's totally out-of-control Grandmere is all set to plan the year's biggest society wedding, with every A-list celeb invited. But will the bride and groom even turn up? And how can Mia find out the true identity of her mysterious secret admirer?
