It's the flight before Christmas, and a woman just got an unexpected surprise: a free first-class upgrade on her trip home for the holidays. Cue the complimentary cocktails! But after a few too many, she ends up spilling all her secrets to the charming stranger seated next to her—only to wake up later, mortified when her buzz has worn off. At least she'll never see him again... or so she thinks.

When she arrives at the festive rental home she's sharing with her family, along with her sister's fiancé and his well-to-do relatives, she discovers the man from the plane is part of the new in-laws. Awkward. Thanks to her tipsy oversharing, he knows all her embarrassing truths—and now they're stuck under the same roof for the entire holiday.

As sparks fly and their chemistry heats up, can they keep things under control long enough to manage the mounting family drama? And what happens when she learns that he has a secret of his own—one that could change everything? One thing is certain: this holiday season is about to get unforgettable.
