The Princess Diaries, Volume IV and a Half: Project Princess

What on earth is that princess up to now?

Hammer in hand, Princess Mia embarks on an epic adventure for one so admittedly unhandy: Along with her cohorts from school, she's off to build houses for the less fortunate. It doesn't take Mia long to realize that helping others -- while an unimpeachably noble pastime -- is very hard work. Will her giving spirit prevail? Will the house collapse due to royally clumsy construction? And most importantly, will Michael stop working long enough to kiss her?

What comes between Volumes IV and V of The Princess Diaries? Volume IV and a Half, of course!
