In fact, *I* want to go on this trip.
However, I certainly wouldn't want to do so with the main character, who, while smart and self-reliant, is entirely too personality-of-a-doormatish to be likeable. She lets everyone shove her around, she ends up in dumb situations because she can't say no or ever express her opinion, and she's spineless.
I have tendencies toward shyness around new people, so I don't think that's what I'm not understanding here. It's more that she is completely disengaged from the world around her rather than just shy.
Nonetheless, the book is certainly charming, and the European travels with the Ghost of Aunt Peg are entertaining enough. I just wanted to see Ginny shaken up, pushed into reacting to something. Yet she is all replete with very her.
I'll take my YA with a side of plucky, please.
