A Kiss at Christmas by Meg Easton

She wants the perfect Christmas. He wants it over already. But fate has other plans.

Kelli just wants a little perfection in her life. Have the perfect Christmas. Be the perfect daughter. Get the perfect parking spot. Be the perfect employee. And pull the perfect pranks on the adorable but off-limits Parker Brockbank in Trade Shows, the guy she went on a first date with two-and-a-half years ago.
The date that was anything but perfect. You don’t always get what you want, and fate has a sense of humor.

Parker wants to ignore Christmas. He usually enjoys it, but since his fiancee broke off their engagement two months ago, canceling his Christmas plans, he doesn’t want anything to do with the holiday. All he wants is to move on and go back to being the Parker that pulls pranks on the charming but off-limits Kelli Ellis from Digital and Print Ads.
