On Thin Ice by Avery Kane

January Jackson and Jake Jeffries have been connected by a single letter their entire lives.
J. Everywhere they turn, there’s a J.
The alphabet forced them together as children. A great dislike for one another forced them apart as teenagers.
Then, in college, they had one drunken night neither of them can explain. They most certainly don’t want to dwell on it.
Ten years later, January is an up-and-comer at Sylvan Slopes, the resort Jake’s father owns. She’s been put in a prime position for the incoming Winter Extreme Games, and she’s getting exactly what she’s always wanted.
Enter Jake. Thanks to his father’s money, he’s spent a decade galivanting about and basically doing nothing to ease himself into adulthood. Why should he when he doesn’t have to? Responsibility is not part of Jake’s world.
Things are about to change.
Jake’s father has given him an ultimatum. He takes a job at the resort or he’s on his own. With no marketable job skills, Jake knows what he has to do. There’s just one problem: January is his boss.
January and Jake have hated each other for a long time. In order to keep a sponsor happy, however, they have to pretend they not only like each other but are married to boot.
The snow—and insults—are going to fly. Along the way, however, they just might find that they have more in common than they ever dreamed of.
Well, if they don’t kill each other first.
