Arianna Worthington proved them all wrong. To the casual observer, she's just a rich and privileged girl with an undoubtedly fabulous future awaiting once she graduates her elite boarding school, but what do they know? The details of her horrific accident last year were well-documented by the press, but a select few know the real story... The "accident" was an attempt at murder, waged by her secret half-sister and ex-bestie, Jess. The ordeal, among other issues, has left Ari traumatized, but she's finally moving forward. The past is over, and she survived—adamant no one will ever hurt her like that again. Except no one told Jess that, apparently. During the beginning of holiday break, Ari receives a card, proclaiming a clear warning: Merry Christmas, little sis! See you soon Vroom! Vroom! Ari doesn't need to be told twice. It's time to run. But where can she go? The Worthington name and money opens a lot of doors, but it's not enough when what a girl really needs is a normal, loving family and some dependable friends. Unless... Maybe there is a place of safety left for her in the world, but she'd better brace herself for a culture shock. A Worthington spending the holidays in the suburbs? Yikes! Follow Ari across the country as she goes on the run, hunted once more by a vengeful psychopath, but all hope is not lost. Maybe this Christmas will turn out better than any other. Or maybe, Jess will get a chance to finish what she started last year. Ari will have to act quickly, adapt, and brush off her survival skills if she wants to vanquish her nemesis for good—and ensure this isn't her last holiday aboveground.
