The first 4 books in a collection
I The Princess Diaries:
One minute Mia’s a totally normal Manhattan fourteen-year-old. Next minute she’s heir to the throne of Genovia, being trailed by a bodyguard, taking princess lessons with her uncontrollable old grandmere, and having a makeover with someone called Paolo. Well, her dad can lecture her till he’s royal blue in the face, but no way is Mia going to turn herself into a style-queen. And they think she’s moving to Genovia? Er, hello?
II Princess in the Spotlight:
Just when Mia thinks she has the whole princess thing under control, things get out of hand, fast. First there’s an unexpected announcement from her mother. Then Grandmère arranges a national primetime interview for the brand-new crown princess of Genovia. On top of that, intriguing, exasperating letters from a secret admirer begin to arrive. Soon Mia is swept up in a whirlwind of royal intrigue the likes of which hasn’t been seen since volume I of the Princess Diaries.
III Princess in Love:
Princess Amelia Mignonette Grimaldi Thermopolis Renaldo may seem like she’s the luckiest girl ever. She’s a princess, for starters. And while she’s no supermodel, mirrors do not crack at her reflection. Best of all, she finally has a boyfriend. The truth is, however, that Mia spends all her time doing one of three things: preparing for her nerve-wracking entree into Genovian society under the slave-driving but elegant Grandmere, slogging through congestion unique to Manhattan in December, and avoiding further smooches from her hapless boyfriend Kenny. All she wants is a little peace and quiet…and a certain someone else to be her boyfriend. For Mia, being a princess in love is not the fairy-tale it’s supposed to be…or is it?
IV Princess in Waiting:
Never before has the world seen such a princess. Nor have her own subjects, for that matter. Mia’s royal introduction to Genovia has mixed results: while her fashion sense is widely applauded, her position on the installation of public parking meters is met with resistance. But the politics of bureaucracy are nothing next to Mia’s real troubles. Between canceled dates with her long-sought-after royal consort, a second semester of the dreaded Algebra, more princess lessons from Grandmere as a result of the Genovian parking-meter thing, and the inability to stop gnawing on her fingernails, isn’t there anything Mia is good at besides inheriting an unwanted royal title?
