You probably did hear it recommended elsewhere, and might be more your pref than mine, given my feelings about musical theatre. I can say at least that the two Ruby books (The Boyfriend List and The Boy Book) are short, and those I'd unequivocally recommend in that looks like chicklet lit but I think it's not category I was just babbling about.

Oh - Justine Larbalestier? I'm sure she was among those raving about Dramarama...
