Now I've read all Sophie Kinsella's books. Ha.

Becky really pissed me off during the 4th book, I knew she was dumb, but I didn't know she could be THAT dumb. Kinsella portrayed Becky's sister as such a frugal person that it felt a little awkward reading the disparate sisters. But I'd say the 4th book is the one with the most adventure among all the books she's written about Becky - literally. I just don't understand how such a dumb person could eventually turn the whole world upside down. Anyway... at least it was pretty entertaining.
