Addie and her sister are on an epic road trip to a friend’s wedding in rural Scotland. But, not long after setting off, a car slams into theirs. The driver is none other than Addie’s ex, who she hasn’t seen since their traumatic break-up two years earlier.

Dylan and his best mate are heading to the wedding too, so Addie has no choice but to offer them a ride. And with four hundred miles to go, they can’t avoid confronting the very messy history of their relationship . . .

Will they make it to the wedding? And, more importantly, is this really the end of the road for Addie and Dylan?
