What's an American girl with a big mouth, but an equally big heart, to do? Lizzie Nichols has a problem, and it isn't that she doesn't have the slightest idea what she's going to do with her life, or that she's blowing what should be her down payment on a cute little Manhattan apartment on a trip to London to visit her long-distance boyfriend, Andrew. But what's the point of planning for the future when she's done it again? See, Lizzie can't keep her mouth shut. And it's not just that she can't keep her own secrets, she can't keep anything to herself. This time when she opens her big mouth, her good intentions get Andrew in major hot water. So now Lizzie's stuck in London with no boyfriend and no place to stay until the departure date written on her non-refundable airline ticket. Fortunately, there's Shari, Lizzie's best friend and college roommate, who's spending her summer in southern France, catering weddings with her boyfriend, Chaz, in a sixteenth-century château. One call and Lizzie's on a train to Souillac. Who cares if she's never traveled alone in her life and only speaks rudimentary French? One glimpse of gorgeous Château Mirac - not to mention gorgeous Luke, the son of Château Mirac's owner - and she's smitten. But while most caterers can be trusted to keep a secret, Lizzie's the exception. And no sooner has the first cork been popped than Luke hates her, the bride is in tears, and it looks like Château Mirac is in danger of becoming a lipo-recovery spa. As if things aren't bad enough, her ex-boyfriend Andrew shows up looking for "closure" (or at least a loan), threatening to ruin everything, especially Lizzie's chance at ever finding real love... Unless she can figure out a way to use that big mouth of hers to save the day.
