When the worst snowstorm of the century hits the Scottish Highlands just in time for the Christmas holiday, Harper knows she must seek shelter from the storm. With her grandparents' home still hours away and the roads growing more hazardous by the minute, she is left with no choice but to take refuge in the one place she swore to never return - McMillan Castle - the home of the only man to ever break her heart.
Christmas only serves to remind Kamden McMillan of all that he's lost. As he settles in for yet another holiday spent alone, he is stunned when his ex-girlfriend breaks into his home to escape the snow. With the storm projected to last for days, Kamden sees this time alone with her as a chance to make things right.
Just as they begin to get reacquainted, Morna's meddling magic sends them back in time, and both are forced to reconsider what they thought they knew about the other. Will returning to the year their relationship ended allow Kamden and Harper to mend the hurt between them? Or has history already sealed their fate?
