Wow, I didn't like that book at all. And I like Meg Cabot, really. Maybe I was under the influence of Attachments, which set the bar too high? 
 The fact is this: I don't even understand why's it called "Queen of Babble". Supposedly, she, the main character (I have forgotten her name already), can't keep her mouth shut, but: I didn't see any evidence of this in the novel? Except in that particular moment, when she vents all her most embarrassing secrets to an complete stranger in a train, who obviously turns out to be "the guy"--a plot already explored in Can You Keep a Secret?, which I seem to remember was a lot more fun. 
 But before I keep listing why I didn't like it (that main character, UGHHH), let me tell you what's about: It's about a History of Fashion major who goes to London to spend the summer with the boyfriend she's only seen 1 day in her life. She's been fantasizing for months about how perfect will it be to live with her adored Andrew, but when the moment arrives it all goes completely wrong. Obviously. Incidentally, you have learnt at the beginning that her best friend and her boyfriend are staying in a villa outside Paris, so, from the beginning, you know that she's gonna end up in that French villa, where she'll find her real (preferably half-French) love interest. 
 I won't say anything more, although it's 100% predictable so I wouldn't spoil the book for you anyway. Instead, I'll tell you why I didn't like it (kind of spoilerish, but not explicitly): 
 - The main character is the worst, she's supposed to be romantic and have this guy (british bf) idealised, but she comes across as dumb and blind to me: the signs are all there from the beginning 
 - I hate it when in books people suddenly discover that their boyfriend/girlfriend is an awful person--HOW DID YOU NOT SEE THIS COMING, YOU ARE DATING HIM/HER. And this happens TWICE in this book. TWICE 
 - It's not consistent at all. As I said, at the beginning she's very gullible and dumb and blind, but for some reason, she's very distrusting of the ~~love interest and gets mad at him for NO REASON, ALL THE TIME 
 - Of course everybody loves the main character (except the mean girl) and I don't understand why 
 - How she did not see ANYTHING coming? 
 I don't know, maybe I shouldn't be that harsh with a fun light ya/chick-lit novel... But why the hell not? There are incredible books in the genre! it feels like Meg Cabot (who, I swear, I adore) felt very lazy when she wrote this.
