Bad heir day - Meg Cabot

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.
