Read the series that inspired the smash-hit Disney film, starring Anne Hathaway!

Princess Mia is at an all-time low. Could her luck be about to change? Bad Heir Day is the ninth entry in the Princess Diaries series by Meg Cabot.

Lilly isn't talking to her. Someone is posting horrible things about her on ihatemiathermopolis.com. Grandmère is forcing her to give a speech to 2,000 of the most powerful businesswomen in America. And, oh yeah. Michael dumped her.

Now, Mia is on a downward spiral - from perfect princess to couch potato, using food to fill the void left by Michael. Now she faces going back to school - where she is already failing - and none of her clothes fit.

But Mia does have more on her mind. Like a 400 year-old mystery that could mean big changes for Genovia. Is she really ready to throw away her tiara?

Continue the royal ride with Crowning Glory, the tenth book in the series.

Previously published as To the Nines, and in the US as Princess Mia.
