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.

PRAISE FOR MEG CABOT

"There is a school of thought that says reading should be entertaining, and this is exactly what Meg Cabot produces for us: fun. She is the master of her genre; she is the George Bernard Shaw, if not the George Eliot of [her genre]." Publishers Weekly

"Cabot has . . . an off-the-wall sense of humor that will have readers laughing out loud and a knack for creating fully realized characters that readers will miss when the story ends." Booklist
