While Mia tries to get over breaking up with her boyfriend, she discovers a diary kept by a former princess of Genovia from the 1600s, the contents of which could change the fate of her country forever.

'You're not Mia Thermopolis any more, honey,' Dad said. 'You're Amelia Mignonette Grimaldi Thermopolis Renaldo. Princess of Genovia.' A PRINCESS?? ME??? Yeah. Right. 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? Meg Cabot's The Princess Diaries inspired the feature film starring Anne Hathaway and Julie Andrews. This beloved series continues in the second book, A Royal Disaster.

Princess Mia is introduced to her Genovian subjects, and more importantly, she goes out on a date with the newly appointed Royal Consort Michael Moscovitz.

From the #1 New York Times bestselling author of the Princess Diaries series, comes the very first adult installment, which follows Princess Mia and her Prince Charming as they plan their fairy tale wedding—but a few poisoned apples could turn this happily-ever-after into a royal nightmare. For Princess Mia, the past five years since college graduation have been a whirlwind of activity, what with living in New York City, running her new teen community center, being madly in love, and attending royal engagements. And speaking of engagements. Mia’s gorgeous longtime boyfriend Michael managed to clear both their schedules just long enough for an exotic (and very private) Caribbean island interlude where he popped the question! Of course Mia didn’t need to consult her diary to know that her answer was a royal oui. But now Mia has a scandal of majestic proportions to contend with: Her grandmother’s leaked “fake” wedding plans to the press that could cause even normally calm Michael to become a runaway groom. Worse, a scheming politico is trying to force Mia’s father from the throne, all because of a royal secret that could leave Genovia without a monarch. Can Mia prove to everyone—especially herself—that she’s not only ready to wed, but ready to rule as well?

With the release of Disney's sequel to the Princess Diaries movie in August, the princess phenomenon will be in full swing in 2004. Girls will be overjoyed with this hilarious addition to their favorite series, which involves seven minutes in heaven, citywide strikes, and Mia's mission to get asked to the senior prom.

Princess Mia Thermopolis has hit an all-time low. Lilly isn't speaking to her. Someone is posting horrible things about her on ihatemiathermopolis.com. Grandmere is forcing her to give a speech to two thousand of the most powerful businesswomen in America. And, oh yeah: Michael, the love of her life, has dumped her. But despite what the press seems to think, Mia has more on her mind than recruiting a new Prince Charming. Like solving a 400-year-old mystery that could mean BIG changes for little Genovia. But is Mia really ready to throw away her tiara - especially if it means destroying a dynasty? Bad Heir Day, previously published as To the Nines, is the ninth in the bestselling The Princess Diaries series by Meg Cabot.
