Mia finds that nothing's simple when you're the new Princess of Genovia. With her mother dating her algebra teacher, a secret admirer sending mysterious e-mails, and a bad case of the hots for her friend Lilly's brother Michael, Mia's discovering that life as Princess Amelia Mignonette Grimaldi Thermopolis Renaldo can feel like a right-royal muddle!

Mia and Michael are finally an item, but Grandmere seems to have other plans. Just before the happy couple's first hot date, an unmissable royal engagement turns up. Could it be that Michael doesn't measure up, and that Grandmere's got someone else in mind for Mia?

Mia is so totally ready to love her life. She has a college boyfriend, no more Algebra and she's writing for the new school 'zine. But Geometry is even worse than Algebra and Michael's busy schedule leaves him no time to email her, let alone see her. And now Grandmere's mysterious surgery means she keeps changing her will. Will life ever be anything other than a right royal muddle for the Princess of Genovia?

Doesn't a nearly sixteen year old deserve a break? Not only has Mia made a total ass of herself dancing with PJ, trying to prove to Michael that she's a super-chilled party girl. She's also bankrupted the student council. Way to go, Princess. Will she win Michael, and will she be able to get the funds for student council back on track?

Mia is about to turn eighteen and has decided to put down her princess pen for good. This is your one and only chance to find out how it all ends.
