Wanted: one hot billionaire to pose as my Christmas boyfriend. Must be willing to make my cheating ex jealous when you kiss me under the mistletoe at all the holiday parties. Bonus points if you make him cry.

To my surprise my billionaire boss is more than up for the challenge of coming down the chimney as my holiday boyfriend. The sexy single dad desperately needs a plus one at a Christmas Eve wedding, where he's the best man and I'm the maid of honor.

And since my ex is in the wedding party too, my boss and I team up as a pair of insta-lovebirds for the holiday season, including during the annual week-long Christmas competition leading up to the snowy destination wedding.

But soon staying up late to string the best popcorn balls ever turns into a scorching night in his arms where the chestnuts aren't the only thing roasting on the open fire.

Can all these winter wonderland nights seeking revenge turn into the real thing when we return to the office? Or are we destined to go the way of a Christmas tree on New Year's?
