Ashley Davison, a graduate student in California, desperately wants to spend the holidays with her family in Seattle. Dashiell Tyler, a former army intelligence officer, receives a job in Seattle and must arrive by December 23. Though frantic to book a last-minute flight out of San Francisco, both are out of luck: Every flight is full, and there's only one rental car available. Ashley and Dash reluctantly decide to share the car, but neither anticipates the wild ride ahead. At first they drive in silence, but forced into close quarters Ashley and Dash can't help but open up. Not only do they find they have a lot in common, but there's even a spark of romance in the air. Their feelings catch them off guard -- never before has either been so excited about a first meeting. But the two are in for more twists and turns along the way as they rescue a lost puppy, run into petty thieves, and even get caught up in a case of mistaken identity. Though Ashley and Dash may never reach Seattle in time for Christmas, the season is still full of surprises -- and their greatest wishes may yet come true.
