When Fiona Ng's best friend, Michael, needs a pretend girlfriend to bring home for Christmas in Arkansas, Fiona girds her loins and steps up. Besides, how hard could one festive family weekend be, anyway?

That's before she meets the boisterous McElroy clan, with accents as thick as a homemade pie crust, and an endless supply of competitive siblings, including Lizzie, Michael's beautiful younger sister.

Lizzie seems to be everywhere, with her intoxicating scent, wandering hands, lingering gaze, and that bright, echoing laugh. The more time Fiona spends in her orbit, she wonders how she can even concentrate let alone pull off a convincing fake relationship.
