My December Darling by Lauren Asher

Every Kringle in Kringletown celebrated Christmas a lot.

But Cole Black on Whistler Lane, unfortunately, did not.

As his fellow citizens decorate their quaint town, brimming with carols and glad tidings, Cole wants nothing more than to hibernate the winter away. But his dreary plans are thwarted when his Christmas nemesis, Storee Taylor, moves in next door to care for her Aunt Cindy. Immediately, the new neighbor turns his life into a real nightmare before Christmas, especially when she decides to enter the town Christmas Kringle contest in honor of Cindy. And better yet, Storee is determined to win.

Over Cole's dead body, she will. With help from his friend Max, Cole decides to enter the competition as well, to beat Storee at her own game by pretending that this hometown grump's heart has grown three sizes this season and he's fallen for the girl next door. And unfortunately for Storee, she has to follow his lead to have a chance at the Christmas Kringle title.

But the competition isn't the only thing that heats up. Cole and Storee's fake relationship becomes very real, and before they know it, they're attempting to hide it from Aunt Cindy. Things get complicated, the competition gets tough, and all it takes is one single night for someone to steal it all...
