Which is your favourite Princess Diaries book?

Which is your favourite in the Princess Diaries series by Meg Cabot? I've just bought and read the 6th one, and it was quite hard to get into at first, but got better. My favourite one's the 5th. I find it's the one that makes you turn the pages the most. I finished it in a single sitting!

A "single sitting" lol ;P I've tried to read them quite a few times, but I just can't get into them. I think they're probably just not my kind of book.... :p
